Hyperthermic edema

Introduction Hyperthermia: In the hot summer months, mild edema of the hands and feet often occurs after outdoor activities. Because warming causes the blood vessels on the body surface to dilate, the blood flow increases, causing an increase in capillary filtration pressure and edema, and the edema disappears spontaneously after cooling or cooling. Clinically more common in women, edema occurs in summer or high temperature environment, can be repeated for many years. Edema is usually in the hands and feet, with a slight depression, accompanied by fatigue, anorexia, etc., after leaving the high temperature environment or after the summer, the edema itself subsides.

Cause

Clinical examination:

For patients with edema, you should carefully ask your medical history to get the cause of edema. Analyze the pathogenesis, diagnosis and differential diagnosis, treatment and prognosis. In addition to asking general medical history data, patients with edema should pay attention to the development of edema and edema in the past. It is persistent or intermittent, tends to improve or worsen, the location of edema, systemic or local limitation.

Differential diagnosis

Hyperthermic edema must be differentiated from the following diseases:

1. Idiopathic edema: Almost exclusively in women, often associated with the menstrual cycle, is considered a response to endocrine disorders. This type of edema is more common in middle-aged women. It has obvious positional adaptability and often occurs in the lower limbs. It often appears when standing upright, walking or tired, and gradually subsides after lying down or sleeping.

2. Menstrual edema: more common in middle-aged women, and has a significant relationship with the menstrual cycle, starting in the beginning of menstruation 7-14 days, first for the eyelids, and later increased, can spread to the whole body. The base weight can be increased by 1-3 kg in about 10 days. When menstruation comes, there is an increase in urination, while edema and other accompanying symptoms are significantly reduced or even subsided.

3. Pregnancy edema: In the middle and late pregnancy, some pregnant women often have different degrees of lower extremity edema, which is light in the morning and heavy in the evening. This is mainly due to the increased uterus compression of the pelvic vein caused by venous return disorder of the lower extremity. Raise the lower limbs, rest in the flat, and the edema often resolves on its own.
