Two litres a day, no added salt, and a persistent headache that I spent a month attributing to the medication.
The test is quick: add fluid and salt for two days and see whether the symptom goes. If it does not, it was not hydration and it is worth a panel.
What I am trying to establish is why hydration goes wrong on this specifically, given that nobody is telling us to drink less.
I would rather have one careful answer than five confident ones.

Electrolyte monitoring on hydration — especially important during early titration when GI effects are most pronounced:
- Sodium: 140 mEq/L (normal, but was low at week 2 from vomiting)
- Potassium: 4.4 mEq/L (supplement if below 3.5)
- Magnesium: 2.0 mg/dL (supplementing with glycinate)
- Phosphorus: 3.6 mg/dL (normal)
Low electrolytes cause muscle cramps, heart palpitations, and fatigue — symptoms often blamed on the medication itself. Check your levels before assuming it's a drug side effect.

Muscle cramps on hydration — anyone else? I was getting severe leg cramps at night, especially calves. Bloodwork showed my magnesium was low.
GLP-1 agonists can cause electrolyte shifts due to reduced food intake and GI effects. Get your electrolytes checked and supplement accordingly. I take magnesium glycinate 400mg + potassium gluconate 99mg daily and cramps are gone.

Mine went the same way, slower.
From the other side of the consultation, briefly.
Helpful anti-nausea foods for hydration users:
- Ginger (tea, chews, supplements — all work)
- Peppermint (tea or oil capsules)
- Plain crackers or rice cakes
- Bananas (easy to digest, replenish potassium)
- Clear broth (hydration + sodium)
- Small amounts of protein (chicken breast, plain Greek yogurt)
Avoid: greasy foods, spicy foods, large meals, lying down after eating. Keep meals small and frequent — I do 5-6 mini meals/day.
