Comedian and actress Amy Schumer has candidly disclosed experiencing significant gastrointestinal distress before and during a recent public performance, attributing the issues partly to her use of the weight loss medication Mounjaro. The star took to Instagram this week to showcase her slender physique in a striking see-through gold minidress at an event, but her caption revealed a behind-the-scenes health struggle.
Medical Challenges During Performance
In her social media post, Schumer expressed gratitude to medical professionals from Mount Sinai and Atria Health for supporting her through the show despite what she described as "gastro issues" leading up to and during her appearance. The Trainwreck star wrote emphatically, "I'm proud I made it through. Oh boy!" highlighting the severity of her discomfort during what should have been a celebratory moment.
Mounjaro's Role in Weight Loss and Side Effects
The 44-year-old celebrity has been publicly open about her use of Mounjaro, a prescription medication that has helped her shed approximately 50 pounds while managing Cushing syndrome. According to medical resource GoodRX, this drug commonly causes gastrointestinal problems because it functions by slowing gastric emptying to promote prolonged feelings of fullness.
The most frequently reported side effects include:
- Nausea
- Vomiting
- Diarrhea
- Constipation
- Abdominal pain
Complex Health History and Treatment Journey
Schumer's health journey has been multifaceted and challenging. After experiencing severe adverse reactions to other weight loss medications like Ozempic and Wegovy—which she discontinued due to unbearable nausea—she found Mounjaro more manageable. Her medical regimen also includes hormone therapy for endometriosis and perimenopause, which she began in 2025 and has reported improving her energy levels, skin condition, and hair health.
Additionally, Schumer manages Hashimoto's thyroiditis, an autoimmune disorder affecting thyroid function that can complicate weight management. She has undergone several medical procedures in recent years, including liposuction in 2022 following endometriosis surgery and a laminectomy in 2025 for a back injury.
Recent Public Appearances and Personal Updates
The Instagram post in question documented Schumer's participation in a New York City event at Carnegie Hall called "Letters Light and Love," where she read historical letters about Jewish experiences. She appeared alongside fellow celebrities Julianna Margulies, Debra Messing, and Judy Gold, expressing pride in her Jewish heritage and connection to ancestors.
This public appearance comes amid significant personal changes for the comedian, who announced her divorce from chef Chris Fischer in December after seven years of marriage. The couple shares a six-year-old son named Gene. Schumer humorously acknowledged her emotional state on Valentine's Day by creating a "crying corner" in her home, demonstrating her characteristic blend of vulnerability and comedy during this transitional period.
Looking Forward with Strength
Despite these health and personal challenges, Schumer recently declared feeling "strong" and "healthy" following her substantial weight loss. Her openness about medical treatments, side effects, and personal struggles continues to resonate with fans who appreciate her authentic approach to discussing often-taboo health topics. The star's journey underscores the complex realities of weight management medications and the importance of medical supervision when addressing multiple health conditions simultaneously.
