The presence of extra pounds is harmful to health, but there are methods of losing weight that are even more harmful. This was told by a nutritionist, Professor Alexei Kovalkov.
In particular, one of the biggest threats to human health are diuretics, if they are used specifically to get rid of excess weight. Both diuretics and laxatives should be used only on prescription and in connection with existing health problems, but not in order to quickly reduce your weight. Firstly, they are absolutely useless for this, and secondly, they can be harmful.

With the frequent use of such drugs, severe renal failure can develop, and in one form or another this pathology already exists in 30% of the inhabitants of our country, who do not even know about it, as Kovalkov noted.
