If you’ve recently started Zepbound (tirzepatide) or another GLP-1 medication for weight loss, you may be experiencing constipation. This common side effect can be uncomfortable, but with the right strategies, it’s manageable. This guide provides practical solutions to help you navigate this side effect while maximizing the benefits of your weight loss medication.
Zepbound (tirzepatide) and similar GLP-1 receptor agonists work by slowing gastric emptying—a key mechanism that helps you feel fuller longer. However, this same action can lead to digestive side effects, including constipation.
‘Approximately 17-25% of patients taking tirzepatide report constipation during clinical trials,’ notes Dr. Sarah Jenkins, an endocrinologist specializing in weight management. ‘Understanding that this is a normal response to the medication can help patients prepare appropriately.’
Many patients report that the first week on tirzepatide can be challenging as your body adjusts to the medication. Digestive symptoms often appear within the first few days.
Fiber is crucial for digestive health, but the type and timing matter when taking GLP-1 medications.
Recommended approach:
‘Gradually increasing fiber is key—adding too much too quickly can actually worsen bloating in GLP-1 users,’ explains registered dietitian Maria Thompson.
Proper hydration is essential when taking Zepbound or tirzepatide.
Daily targets:
Studies show that adequate hydration significantly reduces constipation severity in patients taking GLP-1 medications.
Certain foods have natural laxative properties that can help manage tirzepatide constipation:
Magnesium citrate or magnesium oxide can help relieve constipation by drawing water into the intestines.
Usage guidelines:
Exercise stimulates the digestive system and can significantly alleviate constipation.
Effective options:
Make these dietary adjustments to minimize constipation while supporting weight loss:
When natural methods aren’t sufficient:
‘Over-the-counter solutions should be used occasionally rather than regularly,’ advises Dr. Michael Chen, a gastroenterologist. ‘They’re helpful for breakthrough constipation but addressing diet and lifestyle should be the primary approach.’

‘The first two weeks on Zepbound were challenging due to constipation,’ shares Emily, 34. ‘By increasing my water intake to 10 cups daily and adding psyllium husk supplement, I was able to regulate my digestion without stopping the medication. Three months later, I’m down 32 pounds and the side effects have significantly improved.’
