The first thing you need to do in this case is to clarify if you have not been drinking water for a long time and if you are sweating a lot. If the symptoms can be relieved after hydration it means that the body is losing water and hydration is fine.
If the symptoms are not relieved, you need to be alert to the cause of diabetes, hyperthyroidism, urolithiasis, or dry syndrome, and you need to see a hospital internal medicine department, or endocrinology and urology to further clarify the diagnosis.
