Endocrinologist Arina Tertyshnaya listed the most common causes of swelling.
The expert notes that swelling does not occur just like that and suddenly, it is a consequence of certain processes within the body. And it is important to find and eliminate the cause.
“The first thing to do is to rule out kidney and heart disease. If there are no such problems, then we look further. Now I will list in order the most popular causes of puffiness, ”says the doctor.
You may be surprised, but often swelling occurs due to lack of sleep. Everything is simple – it is at night, during sleep, that the body reboots and restores all systems. If we do not sleep enough, a number of important hormones (cortisol, growth hormone, estradiol) begin to fail, and in the morning we see the result in the mirror.
The second major reason is insufficient water intake. It would seem, where to drink even more, if there are already swelling. The mechanism is extremely simple – with a shortage of water, the body begins to store it for the future, and does this by forming edema.
Another common reason is stagnation in the lymphatic system. Here, everything is connected with other reasons – both with lack of sleep, and with a lack of water in the body, and with the work of the intestines. Lymph simply does not have time to remove all the dirt from the body.
Hormonal imbalances are a serious risk factor. In particular, this applies to women with progesterone deficiency, they are more prone to the formation of edema.
