The second point is body puffiness, because the main function of the kidney is to excrete water and excrete excess water from the body. If a person's kidney has a problem, then the water in his body will not be discharged, which may lead to obesity. This kind of obesity can make you feel weak, and sometimes you even feel fat without eating or drinking. At this time, you should pay attention. Maybe there is something wrong with your kidney. Don't be careless.
The third point is mainly urine, from which we can see many diseases, including kidneys. Because the main function of the kidney is to drain water, urination is also its duty. A person in kidney is not good usually urinates frequently, urgently and endlessly, and there are many bubbles in his urine. These phenomena have been experienced by people with kidney function problems, so everyone should pay attention.
The fourth point is that the body is particularly weak, feeling cold sweat in summer and hot in winter. Generally, people with kidney function problems will have their own endocrine disorders, which are not consistent with the feelings of normal people. Normal people will feel hot in summer, but people in kidney is not good will catch cold and cover themselves up, which is also a sign of kidney problems.
