Pregnancy-Related Insulin Toxicity


Gestational Diabetes Is a Misnomer. Pregnancy-related Insulin Toxicity Is the Appropriate Term. I Explain.

Majid Ali, M.D.


 Three Reasons For Preferring Pregnancy-Related Insulin Toxicity

  1. The term gestational pregnancy clearly implies that diabetes is related to the fetus and can be expected to clear out by itself when the pregnancy ends. This is a regrettable misunderstanding. Various publications on the subject have reported that diabetes Type 2 developes in 30-50% of women in 3-10 years.
  2. There is no agreement on the criteria for the diagnosis of gestational diabetes. By contrast, there can be no disagreement on the concentration of blood insulin concentrations. Good laboratories can perform insulin tests with a high degree of precision and accuracy.
  3. Insulin profiles determined following a standard 75-gram glucose challenge provide precise numerical values for the fasting, 30-minutes, 0ne-hour, two-hour and three-hours blood samples.
  4. I have used the fasting and peak insulin concentrations in a 3-hour profile to be extremely valuable, both for the patients and the clinician.
