General Discussion

Conn Syndrome is characterized by an increased level of the hormone aldosterone in the blood causing increased sodium levels in the blood. An increase in blood volume (hypervolemia), and a low potassium level (hypokalemic alkalosis) also occur. This disorder is characterized by periods of weakness, unusual sensations such as tingling and warmness, a transient paralysis, and muscle cramps. An increase in blood pressure (hypertension), excessive urination (polyuria), and excessive thirst (polydipsia) can also occur.
