Starting Mounjaro is a big and positive step toward your health goals. But dealing with an upset stomach and other side effects can be a real challenge. If you find yourself running to the bathroom more than you’d like, please know that you are not the only one.
This leads to one of the most common questions that people ask: “Does Mounjaro cause diarrhea?”
We are here to give you a very clear “yes” to that question. We will also explain the simple reasons why this happens. Most importantly, we will give you a complete relief toolkit packed with easy tips to help you feel better fast.
Diarrhea is a Very Common Side Effect
Let’s get right to the point. Yes, diarrhea is one of the top stomach-related side effects of Mounjaro. It’s right up there with feeling sick to your stomach, which is called nausea.
It’s actually a sign that your body is starting to adjust to the powerful way that the medicine works. It can be uncomfortable, but it’s very normal.
The best news is that for most people, the diarrhea is most noticeable when they first start treatment. It also might pop up when the dose is increased, but it tends to get much better over time.
Why Does This Happen?
It can help to know why your body is reacting this way. Mounjaro works by copying special hormones in your body. These hormones change how your whole digestive system works.
Sometimes, the medicine can make your digestive system speed up. This can cause the food you eat to move through your body too quickly. When that happens, your body doesn’t have enough time to absorb all the water from the food, which results in diarrhea.
You can think of your digestive system like a highway. Mounjaro sometimes changes the speed limit on that highway. Your body just needs a little bit of time to get used to the new pace.
How to Feel Better Fast
You do not just have to suffer through this uncomfortable side effect. There are many simple and effective things you can do to get relief. This is your personal toolkit for feeling better.
Change Your Diet
When your stomach is upset, one of the best things you can do is change what you eat. A special diet called the “BRAT” diet is famous for helping with diarrhea. BRAT stands for:
- Bananas
- Rice (plain, white rice)
- Applesauce
- Toast (plain, white toast)
These foods are great because they are very bland and low in fiber. This helps to make your stool more firm and can calm down your upset stomach.
Foods to Avoid When You’re Having Trouble
Just like some foods can help, other foods can make diarrhea much worse. While your stomach is feeling sensitive, it’s a good idea to avoid these common triggers:
- Greasy, fatty, or fried foods
- Very spicy foods
- Foods with a lot of sugar, like candy or regular soda
- Dairy products like milk and cheese
- High-fiber foods like raw vegetables or beans
Hydration is Your #1 Priority
This is the most important rule of all. Diarrhea can make your body lose a lot of water and important minerals very quickly. This can lead to dehydration, which can make you feel even worse.
You need to make sure you are replacing all the fluids you are losing. The best way to do this is to sip on liquids all day long. Water is great, but you can also try clear broths or special drinks with electrolytes, like sports drinks.
Over-the-Counter Options (Talk to Your Doctor First!)
There are medicines you can buy at the pharmacy that can help with diarrhea. These include common ones like Imodium or Pepto-Bismol.
However, this is very important: You must talk to your doctor or pharmacist before you take any new medicine. They need to make sure it is safe for you to take with Mounjaro and any other health conditions you might have.
When Does the Diarrhea Get Better?
It can be very reassuring to know that this feeling won’t last forever. For most people, the diarrhea is most common during the first few weeks of taking Mounjaro. This is when your body is doing the most adjusting.
Many people ask, “Does Mounjaro cause diarrhea to flare up after a dose increase?” The answer is often yes. Each time your doctor increases your dose, you might have an upset stomach for a few days as your body gets used to the new, stronger amount of medicine.
Understanding your dosing schedule can help you be prepared. You can review the typical steps with a Tirzepatide dose calculator.

When to Call Your Doctor: Important Safety Warnings
Most of the time, diarrhea is just an uncomfortable side effect. But sometimes, it can be a sign of a more serious problem. You should call your doctor if:
- The diarrhea is very severe and it lasts for more than a couple of days.
- You see signs of serious dehydration. This could be feeling very dizzy, having a very dry mouth, or not peeing for many hours.
- You have a fever or you see any blood in your stool.
- You are having very bad stomach pain along with the diarrhea.
For any concerns, it’s always best to reach out to your medical team. You can send a message through your patient portal or find their information on their contact page.
