Lexapro appetite control: what to expect and how to manage it
Starting Lexapro (escitalopram) often brings changes in appetite. Some people feel less hungry at first. Others notice increased cravings or slow weight gain after weeks or months. That can be unsettling, but understanding typical patterns and practical steps makes this much easier to handle.
How does Lexapro change appetite? It alters serotonin signaling in the brain. Serotonin helps regulate mood and appetite. When this balance shifts, your hunger signals and food reward can change too. Early on you may lose appetite or feel nausea for a few days to weeks. For some people appetite returns and eating habits shift, which can lead to gradual weight gain.
Timing matters. Many people see appetite suppression in the first 2–6 weeks. If weight changes happen, they usually show up after a few months on treatment. That doesn’t mean everyone will gain weight—responses vary a lot. Keep an eye on trends rather than day-to-day fluctuations.
Practical ways to control appetite on Lexapro
Use simple, realistic steps you can stick with. Small habits add up.
- Weigh weekly, not daily. Weekly checks show real trends and avoid anxiety over normal fluctuation.
- Eat protein and fiber at meals. Protein and fiber keep you full longer and reduce snacking urges.
- Plan three meals and two small snacks. Regular meals prevent extreme hunger that triggers overeating.
- Hydrate before reaching for food. Thirst often looks like hunger; a glass of water can help.
- Keep trigger foods out of sight. If chips or sweets are easy to grab, you’ll eat them more often.
- Move daily. Even a 20–30 minute walk helps appetite regulation and mood.
- Manage nausea. If food feels off, try bland small meals, ginger tea, or eating cold foods that smell less.
If you’re already on other medications, be aware they can change appetite too. Steroids, some antipsychotics, and certain anticonvulsants are known to increase hunger. Stimulants and some migraine drugs can suppress it. Tell your prescriber about every medication and supplement you use.
When to contact your doctor
Call your prescriber if you notice rapid weight gain or loss, new or worsening metabolic issues (like high blood sugar), severe nausea that stops you eating, or if appetite changes come with worsening mood or suicidal thoughts. Don’t stop Lexapro on your own—sudden stopping causes withdrawal symptoms. Your doctor can adjust dose, switch drugs, or refer you to a dietitian.
Final practical note: track what you eat and how you feel for a few weeks. That record helps your clinician make clear decisions. Appetite shifts on Lexapro are common and manageable with small daily choices plus medical support when needed.
