Difficulty Gaining Weight, Evn with Large Appetite

Difficulty gaining weight, even with a large appetite, is a symptom of an overactive thyroid. The thyroid gland and the hormones that it produces, act as an accelerator for the metabolism. Increased thyroid hormone can be produced from a thyroid tumor, or by a diffuse goiter, as in Grave's disease, which is marked by increased levels of thyroid stimulating immunoglobulins.

This symptom is also seen in people with intestinal parasites or extreme cases of dysbiosis. The increased levels of mircoorganisms will use the food consumed as their source of energy, this depriving the "host" of the nutrients ingested from their meals.
