5 Surprising Ozempic Side Effects Doctors Are Finally Revealing (Like Back Pain and Hair Loss)
From back pain that won't quit to a strange new phenomenon called 'Ozempic vulva,' here's the full truth behind GLP-1s
Before you chalk up health bothers like back pain or hair loss to perimenopause or aging, there’s another possibility you might not have considered: Ozempic. While your doctor likely covered the common side effects of GLP-1 meds such as nausea or GI upset, there are several surprising symptoms that often catch women off guard. If you’re taking Ozempic or considering it, here’s what doctors want you to know about the side effects that don’t always make it into the conversation.
What is Ozempic?
You’ve likely heard plenty about GLP-1 medications and weight-loss drugs in general, but let’s focus specifically on Ozempic (semaglutide) and what makes it unique.
“[Ozempic] is a drug that mimics the GLP-1 hormone naturally found in our body,” says Ben Johnson, MD, founder of OSMOSIS. “This hormone makes us feel full and it increases insulin, which lowers blood sugar.”

“Its primary FDA-approved indication is type 2 diabetes management,” says Michael Snyder, MD, Medical Director of the Bariatric Surgery Center at Rose Medical Center and in-house obesity specialist at FuturHealth. “The improvements in weight, blood pressure and cardiovascular outcomes are well-established benefits, but technically, those are secondary for Ozempic specifically.”
Who’s a good candidate for Ozempic?
As beneficial as Ozempic can be, the GLP-1 agonist is not the right fit for everyone.. Dr. Snyder says good candidates for Ozempic usually include:
- Adults with type 2 diabetes
- Overweight or obese adults who have tried lifestyle changes but need additional medical support
Dr. Snyder notes that semaglutide GLP-1s like Wegovy are typically prescribed for weight loss. And although people often refer to Ozempic in the context of weight loss, using it for anything other than diabetes management is technically considered “off-label” use.
Dr. Snyder says those who might not be a good fit for Ozempic include:
- People with a history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 (MEN2)
- People with a history of severe pancreatitis
- People with GI motility disorders (digestive movement issues such as gastroparesis)
- People who are pregnant or breastfeeding
- People who cannot tolerate the GI side effects even at low doses
5 surprising Ozempic side effects doctors are discussing
While you’d expect to get your blood pressure under control and likely lose a little weight while on Ozempic, there are unexpected side effects of the GLP-1 med that many are not aware of. They include:
‘Ozempic vulva’
You may have seen the term “Ozempic vulva” on Reddit and social media platforms like TikTok, but what does the term actually mean? “‘Ozempic Vulva’ is a description of some of the physical changes of the outer female genital area that some have experienced while taking Ozempic,” says Karla Robinson, MD, FAAFP, TwentyEight Health Clinician Lead. “These changes may appear as sagging of the vulva or even a change in the texture of the skin, causing it to feel dry. This is not because of a direct action of the medication itself, but rather due to the rapid weight loss that some experience on Ozempic. Just as Ozempic can cause noticeable fat loss in other areas of the body [like ‘Ozempic face’], it can also cause fatty tissue to decrease in the vaginal area as well.”
What to do: Dr. Robinson and Dr. Snyder both recommend speaking with a doctor or healthcare provider about any vaginal changes, since other conditions can cause similar symptoms. Dr. Snyder notes that the persistent vaginal irritation some people assume is a side effect of Ozempic could actually be due to dermatitis or an infection. Dr. Snyder also suggests staying well hydrated, using a gentle fragrance-free moisturizer and avoiding tight clothing and scented soaps.
Back pain
Has your back been hurting lately, even though nothing in your routine has changed? Many women on Reddit and other platforms have reported the same surprising symptom while losing weight on Ozempic.
“Back pain is not one of the most commonly listed side effects, but it does appear in post-marketing reports and patient experiences,” says Dr. Snyder. “While not as common as nausea or constipation, it’s a real and understandable symptom that can arise during early treatment.”
Dr. Snyder says there might be several factors causing back pain while using Ozempic, including:
- Rapid weight loss changing posture and muscle support
- Constipation or GI pressure causing pain that feels like it’s coming from your back
- Dehydration and electrolyte shifts leading to muscle spasms
- Pancreatitis, which can cause pain that radiates to the back and needs urgent medical attention
What to do: “My first step is to screen for any red flags, such as severe or persistent abdominal pain radiating to the back,” says Dr. Snyder. “An evaluation by your medical professional is worth having if you are concerned.”
After speaking to a medical professional about your back pain and ensuring it’s not due to a more concerning cause, Dr. Snyder recommends:
- Gentle stretching
- Core support exercises
- Staying hydrated and getting enough electrolytes
- Alleviating constipation
- Reviewing any recent Ozempic dose changes
“Often, a simple dosing adjustment or hydration strategy resolves the issue quickly, but patients should always notify their clinician if the pain continues or worsens,” says Dr. Snyder.
Feeling cold
Dr. Snyder says lower body fat and slower internal heat production can make some people feel unusually cold, a surprising side effect of Ozempic.
What to do: He recommends dressing in layers and increasing your protein intake. Since your body requires more energy to digest protein, it gently raises your internal temperature (a process known as the “thermic effect of food.”)
Menstrual changes
Hormonal shifts that happen during rapid weight loss, such as when taking Ozempic, can lead to cycle changes. As a result, your cycle may become shorter or longer, and your periods may become lighter or heavier (or you may even skip one entirely).
What to do: To help regulate your cycle while on a GLP-1 like Ozempic, Dr. Snyder recommends prioritizing balanced nutrition. Eating enough protein, healthy fats and fiber supports steadier hormones during weight loss, which may help keep your cycle on track. He also recommends tracking your cycle. This can help you spot changes early and share clear patterns with your doctor.
Hair loss
Some degree of hair loss is often an unavoidable part of aging for many of us. However, if you notice an uptick in hair thinning or shedding since starting Ozempic, the GLP-1 may be to blame. Dr. Snyder says temporary hair shedding is a common response to metabolic stress during weight loss.
What to do: To halt hair loss and encourage healthy new growth, Dr. Snyder advises checking your iron levels (a deficiency makes it harder for the body to carry nutrient-rich blood to hair follicles) and increasing your intake of protein, a key building block for healthy hair.
Side effects on Ozempic: when to worry (and when not to)
The bottom line? While these side effects might sound concerning, knowledge is power. Dr. Snyder says not to panic if you begin experiencing unusual side effects with Ozempic. “Track your symptoms, communicate early with a provider and remember that GLP-1 medications work best when personalized and when managed by your medical team,” he notes.
By staying informed and proactive, you can make Ozempic work for your unique health goals—and feel confident and supported while doing it.
