GLP-1 Side Effect Risk Calculator

GLP-1 agonists work by slowing gastric emptying (how fast food leaves your stomach) and signaling the brain to feel full. This slowed digestion is the primary cause of nausea, bloating, and vomiting. When the dose is increased too quickly, the body cannot adapt fast enough, leading to acute GI distress. This is why a strict 4-week titration schedule is clinically mandated.

A "GLP-1 crash" occurs when the drug concentration in the blood rises faster than the gut can tolerate. Symptoms include persistent vomiting, inability to keep fluids down, and severe abdominal pain. In rare cases, this can lead to pancreatitis or gastroparesis (stomach paralysis). If you experience severe pain radiating to the back or persistent vomiting, seek medical attention immediately.

To mitigate risks: 1. Prioritize hydration (drink 2-3L of water daily) to avoid constipation and kidney stress. 2. Eat small, bland meals (avoid high-fat or spicy foods). 3. Use "protein-first" eating to maintain muscle and satiety. 4. If nausea is severe, consult your doctor about staying at the current dose for an extra 4 weeks before escalating. 5. Inject in the thigh rather than the abdomen, as some users report slower absorption and fewer side effects.

Yes. Most patients experience a "peak" in side effects during the first 2 weeks after a dose increase. After 3-4 weeks, the body typically acclimates, and symptoms subside. This is precisely why the standard titration is 4 weeks per step—it allows the "peak" to pass before adding more medication.
