What causes excessive thirst and urination?

Hello,

Welcome to icliniq.com.

I can understand your concern regarding increased thirst and frequent urination.

Frequent urination may occur due to various reasons like high blood sugar levels, diabetes insipidus, overactive bladder causing frequent urges, and other psychogenic reasons. It is not always necessary that kidneys are the reason for frequent urination, hormonal disbalance may also cause it. I suggest you follow the below-mentioned instructions

1. Get urine osmolality and serum osmolality tests done.
2. To rule out hormonal causes, get calcium and thyroid profiles.
3. Measure the amount of total urine output per day and water intake and let me know.
4. If you have an uncontrollable, frequent, and strong urge to urinate, then bladder contractility and holding capacity needs to be evaluated.

I hope this information will help you.

Thank you.

Hello, welcome back to icliniq. When you feel urge to urinate that is mostly because of the bladder issue. If it was tubular necrosis then creatine and urea should raise and your urine output should decrease. I would advise you to get a consult with a urologist to get urodynamic studies, it would measure your bladder holding pressure and sphincter pressure. Urine and Serum osmolality can be done to look for concentrating ability of kidneys. Do not worry, its not your kidneys, tubular injury doesn't present like this. It's most likely the bladder holding capacity, so I advise you to get the test done.. Hope this helps. Kindly revert back in case further query.
