Things that happen when you stop taking Mounjaro<\/span><\/h2>\n

Mounjaro mimics the action of glucagon-like peptide-1 (GLP-1) hormone and glucose-dependent insulinotropic polypeptide (GIP) produced by your body to stimulate the release of insulin, increase feelings of fullness, and increase the time it takes for food to travel out of your stomach. These effects help suppress appetite to spur weight loss and regulate blood sugar. Discontinuing the medication reverses the effects, which can cause a resurgence of hunger and dysregulated blood glucose, among other issues.<\/span><\/p>\n

Appetite changes<\/span><\/h3>\n

Mounjaro reduces your appetite by slowing gastric emptying and promoting satiety. \u201cWhen discontinuing Mounjaro, patients might experience a rebound in appetite,\u201d says Alex Foxman, MD, the medical director of <\/span>Achieve Health and Weight Loss<\/span><\/a>. After all, part of the reason the medication works is that reduced hunger leads to better portion control.<\/span><\/p>\n

Before you stop taking Mounjaro, make sure to have lean proteins, whole grains, fruits, and vegetables on hand. Sticking to the healthy diet recommended while taking Mounjaro can help limit increased hunger after stopping the medication. That also means trying not to overindulge in excess sugar, processed snacks, fried foods, and alcoholic beverages when your appetite rebounds.<\/span><\/p>\n

Blood sugar issues<\/span><\/h3>\n

Mounjaro mimics the glucagon-like peptide-1 (GLP-1) hormone to increase insulin secretion and decrease glucagon production, which can help lower blood sugar levels for people with Type 2 diabetes. Stopping the medication can cause your blood sugar levels to return to what they were before you started taking the medication.<\/span><\/p>\n

Weight gain<\/span><\/h3>\n

If you take Mounjaro long-term, you may lose up to <\/span>a quarter of your body weight.<\/span><\/a> If you stop taking Mounjaro, you\u2019ll likely regain at least some of that weight. A placebo-controlled, randomized clinical trial on the effects of stopping Mounjaro after an intense 12-week cycle revealed that some patients regained up to one-third of their lost weight. It\u2019s crucial to continue the healthy habits you adopted when beginning Mounjaro, including diet modifications and increased exercise, as these tend to decrease the amount of weight gained after stopping the medication.<\/span><\/p>\n

Digestive upset<\/span><\/h3>\n

Vomiting, constipation, and diarrhea are common side effects of Mounjaro that often subside once your body gets used to the medication. When you stop Mounjaro, you can expect a similar reaction, such as abdominal pain, nausea, and digestive issues, as your body adjusts.<\/span><\/p>\n

Side effect resolution<\/span><\/h3>\n

If you experience side effects while taking Mounjaro, they will resolve over time after stopping the medication at varying intervals. While time frames for symptom resolution will be different for everyone, here are some general guidelines based on <\/span>Mounjaro\u2019s half-life<\/span><\/a>:<\/span><\/p>\n
