Exploring “The Thin Line” of GLP-1 Drugs

GLP-1 medications, marketed under names like Ozempic, have aided countless individuals in achieving weight loss and managing diabetes, though they come with their own set of issues. A closer look at the possible downsides is worth it.

Christine Reed Smith, a 50-year-old salon owner from Columbia City, Oregon, explored various avenues for weight loss, including consulting a nutritionist in Mexico and even undergoing weight loss surgery. Yet, her struggles continued—the scale kept tipping upward, causing her body to become insulin resistant.

Now, she’s turned to tirzepatide, a key component in GLP-1 therapies like Mounjaro and Zepbound, hoping it will help regulate her blood sugar effectively.

While she achieved her desired physique, it came with unexpected changes. “I found that I was less interested in sex,” Reed Smith remarked.

Throughout her 17-year marriage, her sexual life has experienced fluctuations, which is pretty common, I suppose. Normally, Reed-Smith felt comfortable and energetic, but since starting her GLP-1 treatment, her libido took a nosedive.

“I still participated, but reaching climax felt like a chore. I ended up feeling guilty, thinking it wasn’t about my husband’s performance at all,” she shared. “It’s like there’s something wrong with me.”

The impact was felt far beyond the bedroom. “When your once-active sex life fades to nearly nothing, it creates a void,” she said. “There was tension and likely hurt feelings on both sides.”

The Impact of GLP-1 on Sexual Desire

GLP-1 medications manage appetite and blood sugar by mimicking gut hormones released after eating, but they can also have unanticipated effects on the brain and body, potentially leading to decreased libido for some.

“The brain’s signals for seeking pleasure can diminish, lowering sexual motivation,” explained Dr. James Chao, co-founder and chief medical officer at VedaNu Wellness in San Diego, who treats patients using weight loss drugs.

However, the effects vary widely; interestingly, some people report an increase in sexual desire following weight loss. “Feeling good about myself makes me want to be active. I can look in the mirror and not feel bad, and that can lead to an uptick in desire,” he said.

CJ Rock experienced this positively before trying GLP-1 medications.

“Losing weight gave me a self-esteem boost, similar to a dopamine rush, making me more interested in sex,” the 47-year-old recalled. Yet, once she began using tirzepatide, the sexual cravings vanished completely.

“I used to have a normal sex drive, around two or three times a week. Then, suddenly—nothing,” she reflected.

“Now, five months in, I didn’t want him anywhere near me. I was like, ‘No, no, don’t even try to kiss me.’

She lost 70 pounds in seven months, but when her fiancé attempted to initiate intimacy, she felt… well, almost numb. “Some nights, I really questioned if I was doing something wrong,” she admitted.

Dr. Chao noted that this scenario is not uncommon. Rapid weight loss from GLP-1 medications can push the body into what’s called “sparing mode,” as it adjusts to diminished food intake.

Moreover, menopause added another layer of complexity for both Reed Smith and Locke, as they navigated the intersection of hormones, aging, and medication effects on sexual desire.

“Once perimenopause begins, changes in sex drive are significant,” Locke observed.

She continued, “Many medical professionals don’t fully address women’s health concerns, leaving those using this drug in similar situations feeling confused—like choosing between two poisons.”

From High Sex Drive to Near None

Interestingly, men and women are affected differently. Take Natalia Souza, 37, from New Jersey. After struggling for three years with diet and exercise to shed just 30 pounds, she turned to tirzepatide and lost an additional 22 pounds over seven months, a result she initially viewed as a success. However, her high libido vanished unexpectedly.

Prior to the drug, she and her husband enjoyed intimacy four to five times weekly. But, after a couple of months on tirzepatide, she found herself resisting any physical closeness. “Five months later, I didn’t even want my husband near me,” she expressed.

Experts agree: GLP-1 medications can trigger varying changes in sexual desire, affecting libido positively or negatively.

Finding Their Sex Drive Again

The sudden drop in Souza’s sexual interest left her contemplating whether the weight loss was worth it. “I can’t let this come between my marriage,” she decided.

Prior to stopping the medication, she tried various supplements like vitamin D and maca root—none of which helped.

“I’d rather be in this body than have an active sex life. What does that mean for me? I’m not sure.”

Then she stumbled upon a supplement designed for natural lubrication and mood stabilization, and gradually, she noticed some improvement.

Reed-Smith, on the other hand, found resolution through a synthetic peptide called PT141, which heightens sexual desire by acting on brain receptors. Approved by the FDA for women with hypoactive sexual desire disorder, it can sometimes be used for men facing erectile dysfunction, too.

After her first injection, Reed-Smith felt a change. “It wasn’t instantaneous, but it felt like coming up for air when you’ve been submerged. I realized I wasn’t broken,” she noted.

Locke, however, took a different approach, emphasizing the importance of patience. “Eventually, my sex drive returned, though it wasn’t super strong. I think my body adjusted to the medication over time,” she shared.

Many physicians recommend being patient, as sexual desire changes can often be temporary. “For most, even if you see a dip, it usually resolves itself,” explained Dr. Fernando Ovalle Jr., a specialist in bariatric medicine. “However, if changes persist, they should be taken seriously.”

Eli Lilly, the producer of Mounjaro and Zepbound (tirzepatide), did not comment on this matter.

No Regrets

Obare highlighted that ongoing research is still unraveling how GLP-1 drugs impact physical health and emotional states. “There aren’t many studies specifically targeting libido—most of what we know is from patient experiences,” he said.

For Rock, the outcome was undeniable: these medications work. “After years of waiting for ‘someday,’ I’m finally living in ‘today.’ It’s given me my life back,” she said.

GLP-1 drugs are intended for long-term use, and many users may regain weight after stopping. Once Souza hits her target weight, she intends to discontinue tirzepatide and manage her health independently.

“The feeling is almost numbing,” she reflected. “I want to feel normal again.”

Reed-Smith, however, has no intentions of stopping the medication. “I’d rather be in this body without the sexual drive,” she said, leaving her with mixed feelings. She hopes others facing similar issues won’t feel alone.

“It’s important for women to realize they aren’t broken because of side effects,” she said. “There are ways to navigate through this.” The journey can be complicated, but support and understanding are crucial.
