Hi, Thanks for writing in. The commonest cause of increased urination a your age is from severe urinary infection. The urinary tract is occupied by many bacteria and this leads to the increased frequency and urge to pass urine. Other causes like diabetes is less likely at your age. Anxiety itself might cause increased urine formation leading to getting up frequently at night to visit the washroom. Please drink around 2 liters of water every day. Doing an urine culture and sensitivity test is also important. It will tell the severe it of infection and if you require a short course of antibiotics to be taken for 5 to 7 days. An urine alkalizer is also good to take. Please do not worry.
