Weight loss medications can be a powerful tool in reaching long-term health goals. However, like all medications, they may come with side effects. The most common ones are nausea, headaches, and fatigue. Here's what causes them and how to manage them effectively. If any of these side-effects persist for a longer period of time, please contact the medical team.
Nausea
Why it happens
Nausea often occurs when starting weight loss medications, especially those that slow digestion or affect appetite regulation. It’s most common in the early stages as your body adjusts.
How to manage it
Take the medication with food (if advised).
Stay well-hydrated.
Eat smaller, more frequent meals.
Gradually increase dosage if recommended by your doctor.
Headaches
Why it happens
Headaches may result from dehydration, blood sugar fluctuations, or the medication’s impact on the nervous system. Changes in diet or routine may also play a role.
How to manage it
Drink enough water throughout the day.
Rest and practice stress-reduction techniques.
Use over-the-counter pain relief (with medical approval).
Monitor your blood sugar if advised.
Persistent headaches should be discussed with the Vi-Lifestyle medical team.
Fatigue
Why it happens
Fatigue is common during the adjustment phase. It can be caused by changes in blood sugar, reduced calorie intake, or increased physical activity.
How to manage it
Prioritize quality sleep (7–9 hours per night).
Eat a balanced, nutrient-dense diet.
Incorporate regular, light physical activity.
Consult your doctor if dosage adjustments are needed.
Constipation
Why it happens
Constipation can occur because many weight loss medications slow down digestion. This reduced gut movement can make it harder for stool to pass, especially in the early stages of treatment.
How to manage it
Increase fiber intake through fruits, vegetables, or supplements
Stay hydrated—aim for at least 1.5–2 liters of water daily
Add gentle physical activity, like walking, to stimulate digestion
Consider using over-the-counter stool softeners if needed (but only after checking with your healthcare provider)
Conclusion
Nausea, headaches, and fatigue are common and manageable side effects of weight loss medications. With the right support and healthy habits, you can minimize discomfort and stay focused on your goals.
