Side Effects Explained
Like all medications, weight loss injections can cause side effects. Most are mild and transient, occurring as your body adjusts to the medication, but it is important to be aware of them.
Common Gastrointestinal Side Effects
The most frequently reported side effects involve the digestive system. These often subside after a few weeks of treatment:
- Nausea: The most common issue. Eating smaller meals and avoiding fatty foods can help.
- Diarrhea or Constipation: Staying hydrated and eating fiber-rich foods is recommended.
- Vomiting: Usually occurs if overeating while on the medication.
- Stomach Pain / Bloating: Feeling uncomfortably full.
Managing Nausea
Since nausea is the primary complaint, here are some tips to manage it:
- Eat slowly and stop when you feel full.
- Avoid fried, greasy, or sugary foods.
- Eat smaller, more frequent meals instead of three large ones.
- Stay hydrated with clear, cold drinks.
Serious but Rare Side Effects
While rare, serious reactions can occur. Seek immediate medical attention if you experience:
- Signs of Pancreatitis: Severe pain in your upper stomach area that will not go away, with or without vomiting.
- Gallbladder Problems: Pain in your upper stomach, fever, yellowing of skin/eyes (jaundice).
- Severe Allergic Reaction: Swelling of face/lips/tongue, trouble breathing.
- Kidney Issues: Little or no urination, swelling in feet/ankles.
Black Box Warning
In animal studies, GLP-1 medications have caused thyroid C-cell tumors. It is not known if this happens in humans. Do not use these medicines if you have a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
