What causes excessive thirst and urination?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am experiencing excessive thirst with a lot of urination, after water intake and I urinate within 30 minutes. Urine appears clear and water and some foam in it. My skin is dry and I suffer from insomnia.

I had a CT scan with IV dye and urine analysis done two months ago and they were normal. Recently I got a blood test done which showed creatinine of 0.64 mg/dL, eGFR of more than 90, potassium levels of 3.83 mEq/L, and sodium levels of 137 mmol/L. BMP basic metabolic panel was fine with no abnormalities. I am concerned about the reason causing my condition. Kindly help.

Thank you.

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.

Patient's Query

Hello Dr.Kathuria, Thank you for your answer. As far as intake and output, I usually drink 2liters per day and urine output is also 2Liters. But what worries me a lot is that urine does not look concentrated. And I feel the urge to pee right after I drink, I am concerned about my kidneys are unable to reapsorb water and concentrate urine. I am also concerned that I had tubules necrosis after the IV dye. It’s been two months and the same issue every day, is this a sign of kidney disease?
Answered by Dr. Yash Kathuria
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.
