Side effects on a vegetarian diet

Nausea (most common: weeks 1–4)

The medication slows gastric emptying, so food sits longer in your stomach. For the first few weeks — especially right after a dose escalation — this can feel like permanent low-grade fullness or actual nausea.

What helps:

• Small, frequent meals— 4–5 small plates beats 2–3 large ones. Half-katori portions.
• Cold or room-temperature food— curd, plain buttermilk, fruit, smoothies tend to go down easier than hot, rich, oily foods.
• Ginger. Adrak chai (light, low sugar), ginger water before meals, or a small piece chewed plain. Evidence-backed for nausea suppression.
• Avoid the trigger trio:deep-fried, very oily, very spicy. Pakoda, samosa, korma — not great companions for week-2 of GLP-1.
• Hydrate between meals, not during. Drinking a lot with food fills you up faster and makes nausea worse.

If nausea is severe enough that you can't eat for >24 hours, message your doctor through the app. They'll usually drop the dose by one step rather than push you off the medication.

Constipation (most common: weeks 2–6)

GLP-1 slows the entire gut, not just the stomach. Combined with eating less and drinking less — the standard pattern in the first month — constipation is almost universal.

What helps, in order of effort:

• Water. Genuinely 3 litres a day. Most patients who fix this fix it just by drinking more.
• Soaked psyllium husk (Isabgol), 1–2 tsp in warm water at bedtime. Cheap, gentle, available everywhere.
• Fibre stack: sprouts, beans, papaya, methi, whole moong, oats. Vegetarians actually have an advantage here.
• A 15-minute walk after dinner. Movement triggers peristalsis. Sedentary evenings make this much worse.

If you've gone four days without a bowel movement, mention it at your weekly check-in. Standard medical laxatives are safe to use on GLP-1; the doctor will recommend one if needed.

Protein gap (silent, can cause muscle loss)

This is the side effect nobody warns you about: when your appetite drops, your total food intake drops, and your protein intake drops even faster — because vegetarians get most protein from dal, paneer, and curd in moderate portions throughout the day, and GLP-1 specifically suppresses appetite for those moderate portions.

You need ~1.4 g protein per kg body weight per dayto protect muscle while losing fat. For someone at 80 kg, that's about 110 g.

Vegetarian protein density that actually fits a smaller appetite:

• Paneer 100 g — 18 g protein
• 1 scoop plant/whey protein with milk — 24 g
• 1 katori cooked rajma — 9 g
• 1 katori sprouts — 7 g
• 2 eggs (eggetarian) — 12 g
• 1 katori dal — 7 g
• 1 katori curd — 7 g

The strategy: at every meal, pick two protein sources rather than one large carb portion. A protein shake once a day covers gaps without sitting heavy.

Fatigue (most common: weeks 1–3)

The first 2–3 weeks, before your body has adapted to the lower intake, you may feel unusually tired around 4 pm. Two fixes:

• Make sure you're actually eating — not just “not hungry, skipped lunch”.
• Check that you're getting B12 and iron (vegetarian-prone deficiencies). Your baseline labs cover this; if either is low we'll supplement.

When to call the doctor (not just check in)

Most side effects are mild and fade in 4–6 weeks. Stop the medication and contact your doctor immediately if you experience:

• Severe, persistent abdominal pain (especially radiating to the back).
• Vomiting that won't stop or signs of dehydration.
• Yellowing of skin/eyes, dark urine, light stools.
• Severe headache, vision changes.
• Signs of an allergic reaction (rash, swelling of face/throat).

These are rare. They're also exactly why your treatment is doctor-supervised, with weekly check-ins, and not bought off a website.
