Increased urination, also known as polyuria, refers to the condition where a person urinates more frequently than normal. This can involve producing larger volumes of urine and may occur during the day or night. Various factors can contribute to this condition, including high fluid intake, certain medications, and underlying health issues. Common causes of increased urination include diabetes mellitus, where high blood sugar levels lead to excess urine production, and urinary tract infections (UTIs), which can irritate the bladder. Other potential causes include kidney disorders and the consumption of diuretics, substances that promote urine production.
