In summer, we drink a lot of water without sweating in an airconditioned room so that excess water is easily accumulated in the body, but we have to be careful about edema that could be a sign of serious diseases.
Edema is the condition that when you press the skin with your finger, the water where is pressed is lost and a dimple is retained for about 10 seconds, while fat is the condition that the pressed area returns very quickly.
Edema caused by normal excess water can be improved by sweating a lot by taking a relaxing bath or exercises.
But if edema is not improved by sweating, there is a possibility of kidney diseases.
When you have kidney diseases, water can be discharged from your body and is accumulated in your body, resulting in edema of the whole body.
Edema in the leg in the morning (Fig. 1) and edema in the face in the evening (Fig. 2) are dangerous.
Edema in the leg in the evening is okay because water tends to be accumulate in the leg that is locate in the lower part of the body during the daytime.
But if you have edema in the leg in the morning, it could be caused by kidney diseases because the leg is not located in the lower part of the body while sleeping. Excessive water retention could be caused by some problems in the kidney.
On the contrary, edema in the face in the evening means that there is a possibility that water could be discharged sufficiently from the kidney as urine.
