Most people on peptide-based treatments like semaglutide or tirzepatide are not drinking enough water. It is not a knowledge problem.

What Happens to the Body During Treatment
GLP-1 agonists slow gastric emptying. Food stays in the stomach longer, and the digestive system operates differently than usual. For people on weekly injections, this effect is constant.
At the same time, many notice increased urination frequency, either through water loss via the kidneys or through diarrhea and gastrointestinal discomfort that causes the body to shed extra fluid.
The combination is straightforward: you lose more water than normal and may not feel thirsty with the same intensity. The body enters a kind of scarcity mode and reduces the urge to drink, even when it needs to.

Some signs indicate your hydration is compromised. Dry mouth that does not go away even after drinking water. Fatigue that is disproportionate to the effort of your day. Headaches that appear in the late afternoon and disappear after sleeping.
Dizziness when standing up quickly from bed or a chair is an important signal. When blood volume decreases due to lack of water, blood pressure drops and the body takes time to compensate.
Dark urine with a strong smell means your kidneys are concentrating waste because there is not enough liquid to dilute it. On hot days or during exercise, this worsens quickly.
