Paradoxically, one cause of hypoglycemia is over-consumption of sugar and other
simple carbohydrates without balancing fats and proteins. When simple carbohydrates are eaten
in the absence of protein or fat, the stomach dumps the entire meal into the blood within
an hour. This spikes insulin production to reduce excess blood sugar by storing it in
the cells of the body. The problem is that, as quickly as the sugar has surged
into the blood and been stored, the sugar falls back off as the stomach empties. However,
the insulin remains in the blood for a while, driving blood sugar to below normal values
- causing hypoglycemia - and the patient "crashes."
On the other hand, if the meal eaten contains a significant proportion of protein, the
stomach spreads out emptying into the blood for up to 2 hours to allow for digestion of the
protein.
If the meal eaten contains a significant proportion of fat, the stomach spreads out
emptying into the blood for up to 4 hours in order to digest the fat.
The slower the rate of dumping of sugar into the
blood, the better insulin production can track the blood sugar level, resulting in a more
stable blood sugar - lower peaks and shallower troughs.
Elevated urinary levels of tartaric acid and other markers of dysbiotic
overgrowth with yeasts and fungi are associated with some cases of
hypoglycemia. This may be due to inhibition of gluconeogenesis by
tartaric acid [Shaw2008].
Hypothyroidism, iodine deficiency, and
adrenal insufficiency are also common in hypoglycemia,
and in most cases, treating these underlying causes results in remission of hypoglycemia
[Barnes1999], [Starr2005, pg 140].
In some cases, hypoglycemic patients may show a heightened sensitivity to insulin, as demonstrated
by the insulin tolerance test
[Barnes1999], [Escamilla1954], [Starr2005, pg 141].
