I get letters

I get so many questions from desperate people all over North America - and sometimes the world - who have many "bizarre and unexplained" symptoms and who need help.

Sometime back in 2005 I received this e-mail:

"Yesterday my doctor ran a 6-Hour Glucose test on me.  My fasting sugar was 71, then after I drank the orange drink:

Hour 1 -  147

Hour 2 - 127

Hour 3 - 104

Hour 4 -  97

Hour 5 -  67

Hour 6 -  84

Do you think this shows that I am Hypoglycemic?

Another letter:

"I'm 55 years old. 40 years ago I had surgery of my left knee. I've had knee pain ever since. I have been contemplating knee replacement surgery because the pain has become relentless and kept me up at night.

Since childhood I've had problems with my feet. I've suffered from depression since my teenager years. Asthma started when I was 21 years old. Low back pain has been my constant companion.

Over the years I went to different chiropractors for chronic low back pain. Nothing was ever solved. Within a few days the same symptoms returned.

I was really sick of being sick. I finally made an appointment with Dr. Z.

I spend 1.5 hours with him. He changed my diet, put me on a regimen of supplements, taped both of my ankles, ordered custom made orthotics.

I must admit that initially I resented having to take all those pills and submit to a really boring diet for candida and hypoglycemia - I was a chocolate addict, I used to have bagels, peanut butter and jelly, plus three 2-3 cups of coffee every morning for breakfast .

To my utter amazement, within a few days my knee pain disappeared completely. I walk faster, with more confidence, not just in a self protective mode.

I've not used an inhaler since I started on Dr. Z's program.

The depression lifted nearly immediately. I find that I need less sleep, I wake up refreshed at 5:00 in the morning.

My food cravings have all but vanished.

Here is a very interesting article from 1966:


"Relative Hypoglycemia as a Cause of Neuropsychiatric Illness," Salzer HM, J Natl Med Assoc, January 1966;58(1):12-17. 38372

Please note that this study was published in 1966.

In studying 300 cases of relative hypoglycemia,

  • symptoms of depression were found in 60%,
  • insomnia in 50%,
  • anxiety in 50%
  • irritability in 45%
  • exhaustion or fatigue in 67%
  • sweating in 41%
  • tachycardia (rapid heart beat) in 37%
  • anorexia in 32%
  • neurological symptoms of headache in 45%
  • dizziness in 42%
  • tremor in 38%
  • muscle twitching in 37%
  • backache in 33%.

During a 6-hour glucose tolerance test the patient would drink a glass of sugar water. Blood sugar levels were monitored at regular time intervals during the six hours following the drink. A potential relative hypoglycemic diagnosis was made if there was a blood sugar drop of 10 to 20 mg% in blood sugar.

It was not necessary for there to be a blood sugar drop into the hypoglycemic range of less than 70 mg%. A patient whose fasting blood sugar is 110 mg% and whose blood sugar drops to 85 mg% during the course of a 6-hour glucose tolerance test has a 25-mg% drop and may have symptoms of hypoglycemia.

  • The fasting blood sugar does not need to be low!

In 185 women and 115 men, the majority of cases were between 30 and 50 years of age, and approximately 50% of the patients had symptoms of over 5 years' duration.

The author feels that

  • every neuropsychiatric illness patient should have a 6-hour glucose tolerance test,
  • especially those who are diagnosed as having psychoneurotic anxiety states or depressive reactions.

The 6-hour glucose tolerance test should be interpreted as positive if there is a blood sugar drop of 20 mg% or more below the fasting sugar level, or if there is a drop from 10-20 mg% below the fasting blood sugar level.

  • A diet high in protein, low in carbohydrate and free of caffeine will result in recovery in about 85% of the subjects.

Here is a stunning research article published in December 2005.

Beginning of quote

Acute Hypoglycemia Presenting as Acute Psychosis

Tanveer Padder MD, Aparna Udyawar MD, Nouman Azhar MD, Kamil Jaghab MD

From the Department of Psychiatry, Nassau University Medical Center, 2201 Hempstead Turnpike, East Meadow NY 11554 USA.


We are presenting a unique case of acute hypoglycemia presenting as acute psychosis with an unusual presentation creating a diagnostic dilemma. Medline search was done using the search words hypoglycemia and psychosis and to the best of our knowledge this is the first reported case of hypoglycemia presenting as acute psychosis.........End of quote

The authors present that hypoglycemia may masquerade as the following disorders:

  • neurologic
  • psychiatric
  • traumatic
  • toxicologic

The authors further note that hypoglycemia has been and can be misdiagnosed as

  • cerebrovascular accident
  • transient ischemic attack
  • seizure disorder
  • brain tumor
  • narcolepsy
  • multiple sclerosis
  • psychosis
  • sympathomimetic drug ingestion
  • hysteria
  • depression

Dr. Z's comments:

  • Fasting Blood Sugar levels are pretty much meaningless.
  • Only a Glucose Tolerance Test can demonstrate your tendency towards hypoglycemia.
  • How fast and how far your blood sugar level drops is of of the essence.

For more than 20 years I have assisted countless clients to help resolve a variety of seemingly bizarre and "unexplainable" symptoms. I dare say that approximately 80-90 percent of the clients who come to my clinic have symptoms of hypoglycemia, candida overgrowth and digestive stress.

I, myself, suffered from terrible depression and mood swings for years and years. Nobody could figure out what was going on with me or how to help me. As soon I became aware of the impact nutrition has on brain function I conducted a food experiment on myself back in 1991. Having grown up in Germany, the land of great beers, breads, pastries, chocolates and wines, I was a complete carbohydrates addict, without realizing it. I cut out all carbohydrates, only ate protein, fat and green vegetables. Within one week most of my severe symptoms had all but resolved.

Obviously, nutrition as being of vital importance for optimum health, has been conveniently forgotten by the medical profession. You mention that word to your MD...most will ignore you, some will belittle you. Most know nothing about it, because that topic was neglected or omitted in their medical school education. So it is not really their fault. Indoctrination goes a long way.

So now, to the advantage of the pharmaceutical industry, it has been made official that all illnesses are really due to a drug deficiency. Just look at American TV commercials. Physicians are pretty much by-passed.

We just don't have enough Prozac in our daily breakfast or lunch or dinner to lead happy and un-depressed lives. (this may sound like a joke, but it really is not funny) Ask you GP. Tell him you don't feel well. He will prescribe you some. You probably can get free samples on-line.

  • Depression, anxiety, panic attacks....are due to Prozac, Zoloft, Wellbutrin, etc."deficiency".
  • Heartburn... is due to a "deficiency" in Tums, antacids, Nexium, Zantac, etc.
  • Pain is due to a "deficiency" in pain medication...Aspirin, Motrin, Vicodin, etc.
  • have headaches? It is probably because you did not take your Aspirin this morning!
  • The list goes on and on
  • Pharmaceutical companies can't make a lot of money if doctors would simply prescribe a change in diet.

There is a pharmaceutical drug for everything, or is there?

  • Hardly anybody asks for the underlying causes of symptoms.

    Of course, what can you do as a physician if the HMO or PPO only allows you an average of 8 minutes per patient?

Clinically useful Hypoglycemia/Candida Support Kits

Dr. Z's Hypoglycemia Support

Hypoglycemia means low blood sugar. The body tries at all times to maintain a nearly constant blood sugar level. This is especially important for the brain and the nervous system...

It is Dr. Z's clinical experience over more than 18 years, that Candida related health problems often occur in conjunction with Hypoglycemia/Blood Sugar issues.
