Polyuria is a condition characterized by the production and excretion of an unusually large volume of urine. Your body typically regulates the amount of urine you produce, but in certain conditions, you may produce excess amounts. Several factors can lead to polyuria, including uncontrolled diabetes, use of diuretics, and exposure to cold temperature. Other common causes are alcohol and caffeine, which both act as diuretics. Initial symptoms usually involve frequent urination, often at night (nocturia), along with constant thirst. Polyuria can dehydrate your body and flush vital nutrients, leading to fatigue and other complications. This condition primarily affects the urinary system, but its causes and effects can involve other body systems, such as the endocrine system in cases of diabetes. With sustained polyuria, the body's balance of fluids and electrolytes can be disrupted, leading to further health problems. Monitoring daily urine output and ongoing medical evaluation can help detect and manage this condition effectively.
