I drink 4 to 5 liters of water daily, including 1 liter extra when going to the gym. But when I drink more, I urinate a lot. I have a problem of frequent urination, and by night while sleeping, I am already dehydrated again. I do not know why this is happening. My urine test was normal, LFT is normal, and CBC is normal. I urinate quite a lot and drink water accordingly. My sugar is normal, including HbA1c. This has been happening since I had stomach issues and digestion problems, probably IBS or something else. I also have a gallbladder polyp as found in USG. Please help me. How can I treat this dehydration problem completely?

Drinking 4 to 5 liters of water will naturally increase urination, and frequent peeing is expected with high intake. If your sugars, urine test, LFT, and CBC are normal, there is no serious concern. IBS or digestion issues do not typically cause dehydration unless you have diarrhea. Try to sip water throughout the day instead of large amounts at once. Add electrolytes like ORS or coconut water if you feel dehydrated. You can book Serum Electrolytes and Creatinine tests to check kidney function and electrolyte balance for reassurance.
