If you’re taking Suboxone (buprenorphine-naloxone) for opioid addiction treatment, you may have noticed some changes in your body—including the number on the scale. Some people report gaining weight on Suboxone, while others see no difference at all.
So, what’s the truth? Does Suboxone actually cause weight gain, or is something else going on?
The short answer: Suboxone itself does not directly cause weight gain, but it can indirectly lead to changes in appetite, metabolism, and lifestyle habits that affect your weight.
In this article, we’ll break down the real reasons some people gain weight while taking Suboxone, how opioid withdrawal affects metabolism, and what you can do to maintain a healthy weight in recovery.
Does Suboxone Directly Cause Weight Gain?
No, Suboxone does not directly cause weight gain—it doesn’t slow metabolism, increase fat storage, or alter hormones in a way that promotes weight gain.
However, several indirect factors might explain why some people gain weight while on Suboxone.
Why Do Some People Gain Weight on Suboxone?
1. Appetite Returns After Opioid Withdrawal
One of the biggest reasons people gain weight in recovery is because opioid use often suppresses appetite.
- While using opioids: Many people eat very little due to nausea, lack of hunger, or a focus on drug use over food.
- After quitting opioids: Appetite returns to normal, and food may start tasting better again.
Solution: If you’re eating more than before, focus on nutritious foods rather than processed, high-calorie meals.
2. Suboxone Can Affect Metabolism
While Suboxone doesn’t directly slow metabolism, opioid withdrawal can temporarily disrupt metabolic function.
- Opioid use can cause insulin resistance, making the body store fat differently.
- Stopping opioids can trigger a metabolic shift, making it easier to gain weight before the body stabilizes.
Solution: Regular exercise and a balanced diet can help reset metabolism faster.
3. Emotional Eating & Cravings in Recovery
Opioids flood the brain with dopamine, the “feel-good” chemical. After stopping opioids, dopamine levels drop, which can lead to:
- Food cravings—especially for sugary or carb-heavy foods.
- Emotional eating as a way to cope with stress, anxiety, or boredom.
Solution: Find healthy dopamine-boosting activities like exercise, music, or hobbies to reduce food cravings.
4. Reduced Physical Activity
Many people move less in early recovery, leading to weight gain.
- Opioid withdrawal causes fatigue, body aches, and low energy, making it harder to stay active.
- Some people stop working out or doing daily activities due to depression or lack of motivation.
Solution: Start small—take short walks, do light stretching, or try low-impact exercises until your energy levels improve.
5. Water Retention & Bloating
Some Suboxone users report feeling bloated or puffy, which may be mistaken for weight gain.
- Opioids affect fluid balance in the body, and stopping them can lead to temporary water retention.
- High-sodium diets or dehydration can also cause bloating.
Solution: Drink plenty of water and reduce processed foods high in sodium.
Does Suboxone Cause Weight Loss Instead?
For some people, the opposite happens—they lose weight on Suboxone.
Why?
- Anxiety or stress in early recovery can suppress appetite.
- Digestive issues like nausea or stomach upset may cause reduced food intake.
- Improved lifestyle choices—some people start exercising more and eating better in recovery.
Bottom Line: Suboxone affects everyone differently—some people gain weight, some lose weight, and some stay the same.
How to Maintain a Healthy Weight on Suboxone
If you’re concerned about weight gain, here are simple steps to stay healthy in recovery:
- Eat Whole, Nutrient-Dense Foods – Focus on lean proteins, vegetables, whole grains, and healthy fats instead of processed junk food.
- Stay Active – Even light movement boosts metabolism and helps mood. Try walking, yoga, or swimming.
- Drink Water – Helps reduce bloating and prevent overeating.
- Find Healthy Coping Strategies – If you turn to food for comfort, explore other stress management methods, like therapy, hobbies, or support groups.
- Be Patient With Your Body – Weight changes in early recovery are normal—your body needs time to adjust.
When to Talk to a Doctor About Weight Changes on Suboxone
If you notice rapid weight gain or loss, or if your appetite changes severely affect your health, you should talk to a doctor.
A doctor can:
- Check for underlying issues like thyroid problems or metabolic changes.
- Adjust your Suboxone dosage if side effects are affecting appetite or digestion.
- Provide guidance on healthy eating and exercise during recovery.
