Erectile Dysfunction Drugs Pose a Risk to Eyes

By | erectile dysfunction, Eye Diseases

A new study from the University of British Columbia, Vancouver, BC showed that erectile dysfunction drugs pose a risk to eyes. UBC researchers studied 213,000 insurance claims of serous retinal detachment, retinal vascular occlusion, and ischemic optic neuropathy. They found that there was a close association with these eye conditions and the use of drugs like Viagra, Cialis, Levitra, and Stendra that these men used for erectile dysfunction (ED). In the year before these men started to take ED drugs none of them had any of these three eye conditions. Once they started taking these drugs there was an 85% increase in occurrence of one of these eye conditions.

Explanation of eye conditions

Serous retinal detachment

Serous retinal detachment can occur when you develop a tear of the retina. In this case the vitreous fluid from the center of the eye can leak underneath the retina and lead to retinal detachment. If you develop spots or floaters or flashes of light, or if you develop weak vision, this is a sign that you should seek immediate help from an eye-specialist.

Retinal vascular occlusion

When a blood clot occurs in either a vein or artery that supplies the retina with blood there can be a sudden loss of vision. This is an emergency and requires a trip to an eye specialist in the hospital.

Ischemic optic neuropathy

The optic nerve collects all the signals from the retina and transports this to the brain for further processing. When the blood supply to the optic nerve gets interrupted, there can be a sudden loss of vision. This is an emergency. An eye specialist has to immediately assess the patient in the hospital.

Eye professor warns to take eye conditions seriously

Professor Dr. Mahyar Etminan from UBC said: “These are rare conditions, and the risk of developing one remains very low for any individual user. However, the sheer number of prescriptions dispensed each month in the U.S. – about 20 million – means that a significant number of people could be impacted.” He went on to say: “Regular users of these drugs who find any changes in their vision should take it seriously and seek medical attention.”

Causation versus statistical association

The study showed a strong statistical association between the ED drug use and these three eye conditions. Patients on the ED drugs were 1.85-fold more likely to develop one of the eye conditions. This was in comparison to controls who were not on ED drugs. Professor Etminan said: “These medications address erectile dysfunction by improving blood flow, but we know that they can also hinder blood flow in other parts of the body”. And he continued: “So although our study doesn’t prove cause and effect, there is a mechanism by which these medications could conceivably lead to these problems. The totality of the evidence points toward a strong link.”

Conclusion

When men age, they often develop erectile dysfunction (ED). ED drugs were developed that can overcome this problem. But like any drug these can have side effects too. One of the rare side effects are three serious eye conditions. The have the name serous retinal detachment, retinal vascular occlusion, and ischemic optic neuropathy. As these men were older, they likely already had some arteriosclerosis of the blood vessels. This means they were at a higher baseline risk to develop one of these eye conditions. A study showed that they were 1.85-fold more likely to develop one of the eye conditions. This was in comparison to controls who were not on ED drugs. At this point the researchers at UBC Vancouver, BC say that they found the following. There was a strong association between ED drugs and these serious eye conditions. They commented that at the present time, however, they cannot say that ED drugs would have caused them.

Every Patient Is Unique

By | Anti-aging medicine, Heart Disease, Hormones, Mental Health, Osteoporosis, Vitamins and supplements, Women’s Diseases

Modern Western Medicine tends to see the disease of a patient as a unique entity. Conventional medicine behaves as if a disease is associated with characteristic symptoms, findings and lab test results, which are then treated in a standard fashion by treating the symptoms of the disease.

The reality though is different: The same disease can present in various patients with different symptoms.

Naturopathic physicians, integrative physicians and anti-aging physicians see patients as unique individuals with characteristic personality traits and slightly varied presentations, which may be shared in a disease entity, but differ substantially from person to person.

It is important to be aware of this uniqueness, if the caregiver wants to achieve the optimal treatment result.

Big Pharma does not like this approach as they would like you to think that the conventional medicine system is superior. A certain disease is treated a certain way, preferably with the most expensive drugs.

I thought that in this blog it would be good to shed some light on this important topic.

Menopausal women with symptoms

Let us consider an example of a 55-year old woman who has hot flashes, dry skin, a loss of hair from the outer aspect of her eyebrows, does not sleep well and has lost her sex drive. She also has put on 20 pounds in the last year despite no change in her diet.

This is how conventional medicine would handle this patient

The doctor examines the woman and does a Pap test as well. A conventional doctor would likely order standard blood tests consisting of a complete blood count, thyroid tests (T4, TSH) and FSH and LH levels. The conventional physician would find that the thyroid hormones are low with a high TSH (thyroid stimulating hormone) and would treat the woman with Synthroid (a synthetic thyroid hormone drug). The LH and FSH were found to be high indicating to the conventional physician that the woman is in menopause. He would offer the standard PREMPRO (a synthetic hormone preparation containing a mare estrogen combination with a progestin) with the warning that he will give her the lowest estrogen combination and only up to 5 years because of the negative findings of the Women’s Health Initiative.

Every Patient Is Unique

Every Patient Is Unique

Here is an example how a naturopathic or anti-aging physician’s would investigate and treat the patient

A naturopathic physician or an anti-aging physician would likely add a female saliva hormone panel to the other blood tests mentioned above and also do a T3 hormone level as part of the thyroid blood tests. The doctor will explain to the patient that she was found to be menopausal and also hypothyroid. With respect to the hypothyroidism the physician will explain that apart from thyroxin (T4) there is a second hormone, triiodothyronine (T3) that is also necessary in order to replace all of the thyroid hormones that humans have. Drug companies assume that T4 (Synthroid) will reverse automatically into whatever amount of T3 the body needs, so they have convinced most conventional doctors to prescribe T4 drugs only (like Synthroid). The problem is that as the body ages, the enzymes necessary to convert T4 into T3 do not work as well as in a younger age.This can be verified by testing T3 and T4 levels simultaneously.

The end result is that the patient who only gets T4 replaced may still have some of the symptoms like lack of energy and depression even when T4 has been replaced. Not so with the patient treated by the naturopath or the anti-aging physician who put our patient on Armour (porcine-derived thyroid hormone replacement containing both T4 and T3).

With regard to the blood tests and the saliva hormone tests the second patient was told that the blood tests confirmed menopause (high LH and FSH) and that the saliva female hormone panel showed what was going on. In this particular patient the female saliva hormone tests showed that the progesterone level was low, the testosterone level was low and estrogen was normal. Another hormone, DHEA-S (which is DHEA sulfate, the storage form of DHEA) was also on the low side. Cortisol that had also been tested was normal. The physician explained that the woman’s adrenal glands showed a slight weakness not producing enough DHEA, which is a precursor to testosterone. The low testosterone level was responsible for her lack of sex drive. Progesterone, which needs to be high enough to counterbalance estrogen, was missing, which was likely the cause of her hot flashes and the lack of energy together with the missing thyroid hormones. The physician explained that the woman needed a small amount of DHEA tablets by mouth, a full replacement of progesterone (through the use of a bioidentical hormone cream) and also a small amount of bioidentical testosterone cream to normalize her hormones.

A reassessment of the patients 2 months later showed that the first woman still had some depression and lack of energy, while the second woman felt her normal self again. Both women had regrown their eyebrows from replacing the missing thyroid hormones and have lost several pounds since the beginning of their treatments, but obviously there were quite different clinical results. The first woman was treated in a “standard conventional medicine” fashion, which will lead to breast cancer as unnecessary estrogen was given. She also will be at risk of getting cardiovascular disease as she was replaced with Progestin, a synthetic drug thought by conventional physicians to represent “progesterone”. The Women’s Health Initiative has proven that this was the outcome with PREMPRO and yet this drug is still on the market!

The second woman received an individualized and personalized holistic treatment protocol. The low progesterone from missing her ovulations after menopause was being replaced and her body very quickly responded favorably by making her feel normal again. The missing adrenal gland hormones and testosterone were replaced and this normalized her sex drive. Both, progesterone and thyroid hormones (T3 and T4) are anabolic hormones and they gave her back her energy and restored her sleep pattern. With normal hormone levels she also lost her depression symptoms.

Two men with depression

If you thought that the difference of these two clinical approaches were just coincidental, think again. The next examples are two men in their early 50’s who see their physicians because they felt depressed and had a lack of energy. Both were normal weight.

Here is the conventional medicine approach

The physician took a history, during which a lack of sex drive was also noted. He examined the patient and came to the conclusion that physically nothing was wrong with the man, but a diagnosis of depression was made. This would account for the tearfulness, sleep problems and loss of sex drive. The doctor prescribed one of the standard antidepressants (in this case sertraline, brand name Zoloft). Three weeks later the patient returned and as he was better, a repeat prescription for the antidepressant was given. After a further two months the patient was reassessed. When the symptoms were reviewed, it became apparent that a lack of sex drive was still present, if anything the patient felt the antidepressant had made this worse. Some of the depressive symptoms have improved on the conventional antidepressant. The doctor discussed that the antidepressant could be increased by one tablet per day. The doctor also discussed the option of using Viagra for the decreased sex drive and difficulty having an orgasm.

This would be the  naturopathic or anti-aging physician’s approach. Again similar to before a history was taken and a physical examination was done. The physician noted that the patient was in the age where a lack of sex drive could indicate an early andropause (the male equivalent of menopause, often difficult to spot with the first presentation). A depression questionnaire indicated that the man was moderately depressed. The patient was sent for blood tests and for saliva hormone tests (a male hormone panel). The physician stated that he would like to arrange for cognitive therapy treatment to sort out the various factors of his depression, but also help his mood by trying to start him on St. John’s wort, an herb that has been proven to be effective for mild to moderate depression. The blood work came back as normal. However, the hormone tests showed that testosterone was in the lower third of the normal range. DHEA-S, cortisol and estrogen were normal. So a few weeks later when the tests had come back the patient was called in.  The doctor explained to him that the low testosterone level would explain why his sex drive had deteriorated along with his symptoms of depression. Bioidentical testosterone cream was added to the antidepressant herbal treatment. The result was that within one month this patient’s sex drive was back to normal. Together with the cognitive therapy treatments and the herbal antidepressant the depression was also resolved. After a further three months of counseling he was able to stop the St. John’s wort. Due to the counseling sessions he felt stronger than ever before and his mood remained stable even when the counseling sessions were terminated. He continued to use the bioidentical testosterone cream regularly.

These are examples of two different approaches in two identical men in their early 50’s. It appears to me that the conventional approach did a disservice to the sick person, only treated symptoms, but did nothing to solve this patient’s real problems. The second case’s depression was treated properly and the physician luckily also did not miss the underlying early andropause with low testosterone levels. Repeat testosterone levels showed a high normal testosterone level, which was now in the upper 1/3 of the normal range.

The conventional approach missed the early testosterone deficiency, which  would cause heart disease, should the testosterone levels become even lower. Viagra certainly would not be the answer as this has a number of potentially serious side effects. The antidepressants at even higher doses would cause more erectile dysfunction, which was what he hoped to have treated.

Conclusion

People often have several conditions at the same time. It takes intuition, readiness to do testing, repeat close observation and repeat examination on the part of the physician. This needs to be coupled with good listening skills to sort out a patient. On behalf of the patient it is important to tell the physician all of your symptoms and observations. Be patient and never give up. A good patient/physician relationship will go a long way in sorting out complex medical problems. Every patient is unique. Not every symptom means the same thing in two different patients.

Early Alcohol Use Will Result In Memory Loss Later In Life

By | Cancer, Health, Heart Disease, High Blood Pressure, Prevention, Substance abuse, Vitamins and supplements

Researchers found that heavy alcohol use in males during midlife paves the way to memory loss from dementia later in life.

I thought that this would be a good topic to review the effect of alcohol in general. Alcohol is a known cell poison, yet cardiologists keep on referring to the beneficial effects of that 1 glass of wine per day that will prolong your life. I will attempt to explain these diverse effects, where small amounts are supposed to be good for you while high amounts can be very damaging.

Review of the effects of alcohol

50% of the world population drinks alcohol, 10% to 20% have chronic alcoholism (Ref.1).  Just recently a Guardian news study was released showing that an astounding 25% of Russian men die before reaching the age of 55, compared to only 7% of men in the United kingdom and less than 1% of men in the US. The study looked at the effects of consuming large amounts of vodka.  There are about 10 million chronic alcoholics in the US. Chronic alcohol consumption leads to 100,000 deaths every year in the US. More than 50% of these deaths are from traffic accidents, the rest from medical problems caused by alcohol (Ref.1). Most of the alcohol gets detoxified through the liver cells and is metabolized into acetaldehyde. This involves the cytochrome P-450 system. That means that when a person also takes narcotics, sedatives or psychoactive drugs that are also metabolized through this liver enzyme system drugs and alcohol are taking much longer to be metabolized. This can lead to lethal overdoses that we hear about on TV all the time, hence the warning that you must not mix alcohol with drugs.

Early Alcohol Use Will Result In Memory Loss Later In Life

Alcohol is a cell and nerve poison. The most vulnerable organs in the body are the liver, brain, heart, pancreas, bone marrow and stomach. So, here are a number of conditions caused by drinking alcohol:

a)    Anemia: When a person drinks heavily and regularly anemia shows up in a blood test. Alcohol has a toxic effect on the bone marrow, which interferes with the production of red blood cells. But certain vitamins required by the bone marrow to manufacture red blood cells are often also missing in the diet of an alcoholic, which contributes to anemia as well.

b)    Cirrhosis of the liver develops in 10% to 20% of heavy drinkers. With cirrhosis part of the liver cells get replaced by fibrotic tissue and in advanced cases this can lead to a hepatic coma and death. Others are developing alcoholic hepatitis. This is an inflammation of the liver with fever and jaundice where the skin and eyeballs turn yellow. It is associated with severe abdominal pain.

c)    Gastritis: Alcoholic gastritis is common, but often undetected. The affected individual may just have stomach pains for a few days, or vomit food and/or blood in addition. With continued use of alcohol it may turn chronic. Alcoholic gastritis can turn into gastric ulcers with massive bleeding that often lead to death.

d)    Pancreatitis: The pancreas is a particularly vulnerable glandular tissue, which gets damaged by regular alcohol intake and with chronic alcohol intake gets partially replaced by fibrotic tissue causing the feared and painful chronic pancreatitis. This is a condition with vomiting and severe abdominal pains that can be unrelenting.

e)    High blood pressure, seizures, dementia, depression, heart irregularities and nerve damage:

You may ask yourself how all of these conditions would be reasonably under one heading. The heading for this is “nerve damage”. Let me explain: The sympathetic nerve is very sensitive to alcohol toxicity and when the sympathetic nerve fibers are damaged, you will develop high blood pressure. You see your physician, get blood pressure medication, but the pressure is difficult to control, if you continue to drink alcoholic beverages. It does not make sense to just add blood pressure pills and hope that this will cure your problem. Seizures are due to direct nerve damage in the more sensitive parts of the brain, which will cause these areas to produce extra electrical activities, which we call seizures. Again, just treating with anti-seizure medications is not the solution. Avoidance of alcohol is the other part of the treatment schedule. Dementia from heavy alcohol use is due to direct nerve atrophy in the brain. Our brain shrinks normally 1.9% to 2.8% per decade, depending on which research papers you read. But in the presence of heavy drinking the frontal lobe of the brain is particularly vulnerable to brain shrinkage.

As this publication shows, mild and moderate drinkers did not suffer more frontal lobe shrinkage than abstainers, but heavy drinkers had a 1.8-fold higher risk of frontal lobe shrinkage on average when compared to abstainers. It was calculated that alcohol had contributed 11.3% to that frontal lobe shrinkage.

The rest of the toxic effect on the nerve tissue explains why depression would develop. The frontal brain contains most of the serotonin producing nerve cells. When serotonin-producing nerve fibers get damaged, the body does not produce enough serotonin to prevent depression from setting in; GABA producing cells often also get damaged, which causes anxiety. It’s not good enough to just prescribe anxiolytic drugs to which the patient will get addicted. The whole person needs to be treated, and abstinence from alcohol has to be part of the program.

Heart irregularities (atrial fibrillation, ventricular fibrillation) can be life-threatening complications due to the toxic effect of alcohol on the nerve fibers within the heart muscle. Emergency physicians are aware of the connection of these conditions to alcohol consumption. Some people’s hearts are more sensitive to the effects of alcohol than others. The most common cause of temporary atrial fibrillation is excessive alcohol intake (holiday heart) according to Ref. 2.

Finally there is the effect of alcohol on nerves in the body. This explains that heavy alcohol consumers can come down with painful pins-and-needles sensations in their hands and feet or with numbness or loss of muscle strength. When the parasympathetic nervous system is affected embarrassing incontinence or constipation can result. Erectile dysfunction in men is also very common. Viagra and continuing to drink is not the solution.

f)      Gout: This painful formation of uric acid crystals in joints can be precipitated in sensitive individuals by consuming alcohol in combination with eating large helpings of beef. There may be a history of gout in the family. Treatment for this is to refrain from alcohol and avoid foods that are leading to uric acid production when ingested.

g)    Cancer: When the body detoxifies alcohol in the liver, the breakdown product is acetaldehyde, which is a known cancer producing substance. A whole array of cancers are known, which come from heavy, chronic alcohol consumption: cancers in the mouth, larynx, esophagus, stomach, pancreas, liver and colorectal cancer have all been linked to excessive alcohol intake.

h)    Cardiovascular disease: heart attacks and strokes can be caused particularly by binging; it is thought that binging makes platelets from the blood more sticky so they clump together and cause blood clots, which in turn leads to heart attacks and strokes.

i)      Infections: Alcohol weakens the immune system, which is another effect on the bone marrow similar to causing anemia, except that this is the toxic effect on the white blood cells and lymphocytes. Heavy alcohol consumers are more prone to pneumonia, to HIV, sexually transmitted diseases, and tuberculosis.

Cardiology view of preventative alcohol

Despite all of these hair raising toxic effects cardiologists have painted the rosy picture that 1 glass of wine for women and 2 glasses of wine for men per day will prevent heart disease. What is the true story here?

Ref.2 points out that there are about 100 prospective studies that confirm that there is an inverse relationship between mild to moderate alcohol consumption and “heart attack, ischemic stroke, peripheral vascular disease, sudden cardiac death, and death from all cardiovascular causes”. It describes further that the reduction of risk in these various studies was persistent and consisted of a 20% to 45% risk reduction. Using blood tests investigators have found that this is because of an increase of HDL cholesterol, reducing blood clotting, making platelets less sticky and reducing inflammation as evidenced by a reduction of the C-reactive protein. Further research has pinpointed that it is the phenols and resveratrol that are contained in alcoholic beverages that are responsible for the beneficial effects. The bad news is that three glasses of wine or more do the opposite, so does binge drinking. Unless you are extremely disciplined and never increase your allowed limit (1 drink for women, 2 drinks for men) you will CAUSE heart disease rather than PREVENT it (Ref.2). Some people have a family history of breast cancer or colon cancer and they should avoid alcohol altogether; also people coming from alcoholic families should avoid alcohol.

Conclusion

Where does this leave us with regard to prevention of heart attacks, strokes and hardening of the arteries in the legs (peripheral vascular disease)? If you are disciplined and stick to the limits, you could prevent 20% to 45% of cardiovascular risk. The brain study mentioned in the beginning of the blog would also confirm that there was no difference between dementia or brain shrinkage when mild to moderate drinkers were compared to abstainers over 10 years. What is not told by the wine industry is that the same effects that prevent cardiovascular disease in mild to moderate drinkers can also be achieved by natural means: exercising regularly will raise your protective HDL cholesterol; taking ginkgo biloba, flax seed and omega-3 fatty acids thins your blood and the platelets are getting less sticky; omega-3 reduces inflammation and resveratrol elongates telomeres making you live longer. At the A4M conference in Las Vegas in December 2011 there were three speakers who pointed out that even small amounts of alcohol will poison mitochondria of your cells and interfere with normal hormone action. This was enough to make me join those who abstain alcohol completely. One thing has not yet been investigated in long-term studies, namely how small effects of alcohol may affect the body over several decades and over an entire lifetime. Despite all the promises of interest groups that red wine is a trendy drink for those interested in heart health, the fundamental long-term studies are missing. What does a guy do with a healthy heart and a brain that is not functioning too well? I just do not want to be the guinea pig in that worldwide study.
