The most common Ozempic side effects, why they happen and how medical follow-up keeps treatment safe.

Common side effects

  • Nausea, especially in the first weeks.
  • Slower digestion, bloating or constipation.
  • Occasional diarrhoea or reflux.
  • Reduced appetite (this is part of how it works).

Most side effects are mild and temporary. They are usually managed by escalating the dose slowly and adjusting timing and diet with your doctor's guidance.
