Chronic pharyngitis is a benign disease that does not cause body wasting even in severe cases. However, it is accompanied by psychosomatic diseases, diabetes mellitus, hyperthyroidism or tuberculosis, and thus body wasting occurs. Chronic pharyngitis is a chronic inflammation that occurs in the mucous membrane, submucous membrane and lymphatic tissues of the pharynx, and patients will have localized symptoms such as foreign body sensation, burning sensation, dryness and itching. Generally speaking, patients with severe chronic pharyngitis will not be affected by their diet, and the disease is benign, so there will be no wasting of the body. However, for some patients with serious conditions, especially those with psychosomatic factors, there may be a loss of appetite, and if they do not pay attention to their diet for a long time, resulting in the total daily calorie intake is lower than the total calories consumed, it will lead to the body to become emaciated. If the patient also has diabetes, hyperthyroidism, tuberculosis and other consumptive diseases, the body will also become thin. It is recommended that patients actively cooperate with doctors to standardize the treatment to avoid repeated attacks. Pay attention to daily diet and strengthen nutritional intake.
