How is finger edema in summer?

The main reason of edema is that too much liquid accumulates in the intercellular space, which leads to the accumulation of water in the body. It may also be frostbite and swelling (of course, this weather is rare). Generally speaking, edema can be divided into two categories: physiological and pathological. Although edema is not necessarily pathological edema, women with edema should pay attention to whether their blood pressure is normal. Any proteinuria or kidney-related diseases? Moreover, if the symptoms can't be alleviated after changing the eating habits, it is necessary to check as soon as possible to rule out the possibility of disease. Pathological reasons: The causes of edema are mostly serious diseases such as cardiopulmonary failure, nephrotic syndrome and cirrhosis. Physiology: the diet is too salty, too sweet, or improper intake of oil. Others, such as standing or sitting for a long time, may also cause poor venous circulation, leading to local (especially foot) body edema or varicose veins.
