Hi and thank you so much for this query. I am so sorry to hear about what your dad has been experiencing. Peeing a lot has to be well interrogated to find out what the possible causes are. Is he urinating several times in small quantities or is he urinating large amounts of urine several times a day? is he having any pains, discomfort or difficulties during urination? Is the urine stream weak? This could be related to prostate pathology, an infection, diabetes, etc. In order to get clues and investigate to establish the cause, please let you father get consulted. His primary care physician would be a great place to start and he shall receive referrals to specialists if need be. Please, drugs are not taken with each symptom. Talk to the doctors and make sure you are getting the indications and use correctly. I hope you find this helpful. Thank you so much for using our services and feel free to request for more information if need be. I wish you the best of health. Thanks. Dr. Ditah, MD
