Ativan (lorazepam) is a widely used anti-anxiety medication prescribed to treat conditions like anxiety disorders, insomnia, and even seizures. While it is known for its calming effects, many people wonder if one possible side effect is increased hunger or weight gain.
In this blog, we’ll take a close look at whether Ativan can cause weight changes, including what the research says about appetite, weight gain, and other related side effects.

Understanding Ativan and Its Primary Uses
Ativan, also known by its generic name lorazepam, is a benzodiazepine that works by enhancing the effects of GABA, a calming neurotransmitter in the brain. This medication is commonly used to treat anxiety disorders, panic attacks, insomnia, and sometimes even bipolar disorder.
Because it slows down brain activity, it promotes relaxation and can help ease symptoms of stress and overthinking. However, like many medications, it can also cause side effects, including some that affect appetite and weight. In some cases, prolonged use may lead to Ativan addiction, especially if not taken under careful medical supervision. This would require enrolling in an Ativan addiction rehab, which will provide the needed medical guidance to restore your sobriety.
Can Ativan Cause Weight Gain?
Although weight gain is not listed as one of the most common side effects of lorazepam, it has been reported by some patients. There are a few possible reasons why Ativan may cause weight gain:
- Reduced activity: This medication can cause tiredness or sedation, making people less active, which may lead to weight gain over time.
- Appetite changes: Ativan affects the central nervous system and may impact appetite control in certain individuals.
- Emotional eating: The calming effects of Ativan may also lead to increased relaxation, which could cause some users to overeat or snack more frequently.
While not everyone taking lorazepam will experience hunger or weight changes, the potential link to weight gain cannot be ignored.
Can Ativan Also Cause Weight Loss?
Yes, in some cases, lorazepam can cause weight loss. This typically happens due to reduced appetite or gastrointestinal side effects. For some users, Ativan causes a decrease in appetite, which may lead to unintentional weight loss, especially with long-term use.
Additionally, if Ativan is being used to treat conditions like anxiety or bipolar disorder, and the underlying condition previously contributed to poor eating habits, changes in weight may reflect an overall improvement or worsening of those health conditions.
Serious Side Effects and When to Get Help
Although Ativan is generally considered safe when taken as prescribed, it can also cause serious side effects. If you notice dramatic weight changes, worsening mood changes, or signs of physical dependence, it’s essential to talk with your doctor or pharmacist. Long-term use of Ativan may also lead to withdrawal symptoms, tolerance, and dependence, especially if stopped suddenly.
Some effects to watch for include severe drowsiness or confusion, worsening depression or anxiety, changes in eating behavior that impact overall health, and withdrawal symptoms such as agitation or sleep disturbances, blurred vision, trouble breathing, memory problems, slurred speech, and suicidal thoughts. In some cases, Ativan may also cause liver problems, allergic reactions, or irregular heartbeat
Always consult your doctor or healthcare provider before adjusting your dosage or stopping the medication.

Managing Weight While Taking Lorazepam
If you’re concerned about how Ativan affects your weight, talk to your healthcare professional. To manage your weight while taking lorazepam, aim to maintain a healthy lifestyle with balanced nutrition and regular physical activity. Pay close attention to your eating patterns and be mindful of any changes in appetite. Try not to rely on food as your main form of relaxation, and consult your doctor if you notice any significant changes in weight that cause concern.
Since lorazepam can cause both weight gain and weight loss, personalized monitoring is key. Each person’s response to the medication may vary based on other medications they take, their overall health, and their mental health condition.
