Zepbound and Wegovy have gained attention as effective options for weight management. Both are prescription medications administered through injections. They help people with obesity or overweight conditions achieve significant weight loss when combined with diet and exercise.
These drugs belong to a class called GLP-1 receptor agonists, but Zepbound also targets another hormone pathway. This dual action sets it apart from Wegovy. Understanding their profiles is key for anyone considering them.
Side effects play a crucial role in deciding between these medications. While they share many similarities, individual experiences can vary. This article dives into Zepbound vs Wegovy side effects to help inform your choices.
Understanding Zepbound and Wegovy
Zepbound, known generically as tirzepatide, is approved for adults with obesity or those overweight with related health issues. It mimics two hormones to regulate appetite and blood sugar. Users typically inject it once a week.
Wegovy, or semaglutide, focuses on one hormone to curb hunger and slow digestion. It’s also a weekly injection for similar weight loss goals. Both require a doctor’s prescription and ongoing monitoring.
These medications aren’t quick fixes. They work best alongside lifestyle changes. Their mechanisms explain why side effects often involve the digestive system.
How Side Effects Occur
Both drugs affect the gut and brain to promote fullness. This can lead to slower stomach emptying, causing discomfort. Side effects usually start mild and may lessen over time as the body adjusts.
Starting at low doses helps minimize issues. Doctors often increase dosage gradually. Hydration and small meals can ease early symptoms.
Individual factors like age, health conditions, and other medications influence side effects. Consulting a healthcare provider is essential before starting.
