If a person wakes up in the morning and has swollen hands, stiff hands, then we can suspect thyroid pathology. After performing the necessary examinations, this diagnosis will be confirmed or we will look for the causes further. Zukhra Pavlova, a well-known Russian endocrinologist, wrote about this in her Telegram channel.  "If a person's face swells first, there are bags under the eyes, and then the swelling kind of spreads to the whole body, then first of all we check the kidneys. Edemas can be localized, such as swollen feet. In this case we should also first look at the heart and the cardiovascular system," explained the specialist.  According to Doctor Pavlova, edema also occurs when there is a lack of protein in the food, usually on some extreme diets. Without protein, it is impossible to retain the liquid part of blood in vessels, and it rushes into tissues, causing edema. "In general, edema can develop in a very large number of pathologies. Very often they develop with cardiovascular diseases. Edema can last for years and can rapidly lead to death - for example, with pulmonary edema. Edema may develop against a background of allergic reactions, infectious diseases, and burns. Edemas occur with a lack of water in the body when the body concentrates fluid in the intercellular space. In any case, you can't fight them with diuretics, you need to go to the doctor and eliminate the cause. Reckless use of diuretics leads to irreversible organic changes in kidney tissue and even cardiac arrest," concluded the endocrinologist.
