Common day to day effects include nausea, vomiting or diarrhea or constipation, early fullness with reduced cravings, fatigue, headaches, and dizziness, often strongest in the first 1 to 4 weeks and easing as your body adjusts. There are several factors to consider, including occasional menstrual changes and temporary hair shedding, plus rare but urgent problems like pancreatitis, gallbladder disease, low blood sugar when combined with insulin or sulfonylureas, and thyroid warnings; see below for week by week expectations, red flag symptoms, and simple steps to reduce side effects that could affect your next care decisions.
Ozempic® (semaglutide) is a prescription medication originally approved to treat type 2 diabetes and now widely used for weight management under medical supervision. It works by mimicking a hormone called GLP‑1, which helps regulate blood sugar, appetite, and digestion. Like any medication, Ozempic can cause side effects. Many women want to know what to expect day to day, which side effects are common, and which ones need medical attention.
This guide explains Ozempic side effects in women using clear, everyday language and information grounded in clinical trials, FDA safety data, and real‑world prescribing experience.
Ozempic slows stomach emptying, reduces appetite, and improves how the body responds to insulin. Because digestion, hormones, and metabolism are closely connected, women may notice physical changes beyond just weight loss or blood sugar control.
Side effects are often dose‑related and most noticeable during the first few weeks or after dose increases.
Most side effects are mild to moderate and improve as the body adjusts. These are the most frequently reported.
Digestive symptoms are the top reason women notice daily changes on Ozempic.
Nausea
Vomiting
Diarrhea
Constipation
These symptoms happen because Ozempic slows digestion. For most women, they lessen over time.
Many women notice daily changes in how food feels and tastes.
These effects are expected and part of how Ozempic supports weight loss. However, not eating enough can worsen nausea, fatigue, or dizziness.
Some women report feeling tired, especially early in treatment.
Possible reasons include:
This usually improves within a few weeks. Persistent or worsening fatigue should be discussed with a doctor.
Headaches are reported by some women, particularly during dose changes.
Contributing factors may include:
Drinking enough water and eating regular, balanced meals can help.
While Ozempic is not a hormone medication, weight loss and metabolic changes can affect reproductive hormones.
Some women report:
These changes are usually linked to weight loss rather than Ozempic itself. Any ongoing or severe menstrual changes should be evaluated by a healthcare provider.
Not everyone experiences these, but some women notice:
Temporary hair shedding
Dry skin
Maintaining adequate protein, vitamins, and fluids is important.
Ozempic does not commonly cause mood disorders, but women may notice:
If you experience persistent low mood, anxiety, or thoughts of self‑harm, speak to a doctor right away.
While rare, some side effects require prompt medical attention.
Symptoms may include:
This is uncommon but requires immediate medical care.
Rapid weight loss can increase gallstone risk.
Watch for:
Symptoms include:
This is more likely if Ozempic is taken with insulin or sulfonylureas.
Ozempic carries an FDA boxed warning based on animal studies showing thyroid tumors. Human risk appears low, but Ozempic should not be used by people with:
Report symptoms like:
Week 1–4
Month 2–3
Longer Term
Dose increases can temporarily bring back earlier side effects.
You should speak to a doctor immediately if you experience:
For milder concerns, tracking symptoms daily can help you and your provider adjust treatment safely.

Many women successfully reduce daily side effects by:
Never change your dose without medical guidance.
Ozempic side effects in women are common, especially early on, but often manageable and temporary. Understanding what to expect daily can help you feel more prepared and confident in your treatment. While many women tolerate Ozempic well, serious symptoms should never be ignored.
Always speak to a doctor about side effects that worry you, interfere with daily life, or could be dangerous. Personalized medical advice is essential for safe and effective use.
