Information on diet
Excessive hunger can sometimes be due to physiological causes such as diabetes, hypoglycemia, hyperthyroidism, or tapeworms. Diabetes mellitus could lead to hyperglycemia or excessive glucose in the blood. The root cause of hyperglycemia, i.e. the diabetes needs to be eliminated in order to restore the normal blood sugar levels in the body. Hypoglycemia, on the other hand, is when the blood sugar levels drop below normal levels. Hyperthyroidism results from an overactive thyroid gland. The thyroid hormone that is secreted by this gland controls metabolic activity and an overactive thyroid gland can change the speed of certain digestive processes. In such cases the increased appetite is actually accompanied by weight loss. In cases of a tapeworm infection the hunger can be accompanied by subtle symptoms like weakness, anemia, and diarrhea.
As some causes that lead to disproportionate hunger can potentially be serious it is best to consult a medical practitioner to rule them out and/or take appropriate treatment if needed.
Sometimes excessive hunger can also result from eating high-calorie food that is not nutrient-rich. Most fast food like burgers, sodas, and French fries fall into this category. So if you tend to eat convenience food such as T.V. dinners that do not provide you with all the nutrients needed for a well-balanced diet, your body may send you signals that it is starved, even though you may have eaten recently. Dehydration can also trigger a false sense of hunger. So make sure you are drinking plenty of clean, pure water.
