Inadequate volume (hypovolemic) hyponatremia. The amount of water in the body is too low as can occur in dehydration. The anti-diuretic hormone is stimulated, causing the kidneys to make very concentrated urine and hold onto water. This may be seen with excessive sweating and exercising in a hot environment. It can also occur in patients with excess fluid loss due to vomiting and diarrhea, pancreatitis, and burns. Hyponatremia may be a side effect of medications, especially diuretics or water pills used to help control blood pressure. This class of drugs can cause excessive loss of sodium in the urine.
