What Happens to Your Body If You Don’t Drink Enough Water? π§
Your body needs water for temperature regulation, blood circulation, digestion, kidney function, and many other processes. Not drinking enough can lead to dehydration, which can range from mild to life-threatening.
Early signs
Thirst and dry mouth
Dark yellow, strong-smelling urine
Urinating less often
Headache or dizziness
Tiredness and weakness
Dry skin
Constipation
As dehydration becomes more severe, you may experience rapid heartbeat, low blood pressure, confusion, fainting, and very little or no urination. Severe dehydration requires urgent medical treatment. (mayoclinic.org

Your kidneys are especially important
Your kidneys need adequate fluid to remove waste through urine. Severe or prolonged dehydration can contribute to kidney stones and kidney problems. (niddk.nih.gov)
How much should you drink?
There isn’t one exact amount that’s right for everyone. Fluid needs vary with body size, activity, temperature, diet, pregnancy, illness, and medications. Water from food and other beverages also counts toward your overall fluid intake.
A simple practical guide is to drink regularly throughout the day and pay attention to thirst and urine color. Very pale-yellow urine generally indicates good hydration, although urine color can be affected by foods, supplements, and medications.
Don’t force excessive amounts of water, particularly if you have heart, kidney, or liver disease or have been instructed to restrict fluids.
If you are confused, fainting, unable to keep fluids down, barely urinating, or extremely weak, seek urgent medical care.
