Recovery After Weight Loss Surgery

What to expect so you can bounce back from bariatric surgery

Considering weight loss surgery but worried about the recovery process? You're not alone. “Many patients have questions about downtime, recovery and when they can return to work after bariatric procedures like a gastric bypass or sleeve gastrectomy,” says Mark Mahan, DO, a Geisinger surgeon specializing in bariatric and foregut surgery.

No matter which type of weight loss surgery you are getting, we'll break down what you can expect, tell you how to avoid complications and offer some tips to make your recovery as smoothly as possible.

What is bariatric surgery?

Bariatric surgery, also known as weight loss surgery, is a set of procedures designed to help people lose weight by altering the digestive system.

"Thanks to modern advancements, complex weight loss surgeries can now be done in a minimally invasive way at top bariatric programs, ensuring your safety. The type of surgery you have is tailored just for you. Some procedures are so safe and efficient that you can even go home the same day," says Dr. Mahan.

Planning for recovery from bariatric surgery

Preparation is key to a smooth recovery. Dr. Mahan advises, "We will help you start to plan for your recovery well before your surgery date. This includes arranging for help at home, preparing meals and setting up a comfortable recovery space."

Arrange for help: Have a friend or family member ready to assist you with daily tasks, especially in the first few days after surgery.
Prepare your meals: Stock up on easy-to-digest foods like clear broths, mashed potatoes and pureed fruits and vegetables.
Create a comfortable space: Set up a cozy area with a comfortable chair, pillows and entertainment to keep you relaxed during your downtime.

Bariatric surgery recovery timeline:

Days 1–3: Restful movement & liquid diet

The first few days after surgery are all about rest and recovery — but that doesn't mean you should stay completely still. You'll likely feel some discomfort, but this is normal.

Dr. Mahan explains, "Managing pain is important during this time. Counterintuitively, the best way to feel better quickly is to start moving early and often."

Why is moving around, or "ambulation," so important? "Short walks and gentle movement help prevent complications and let you test out your daily routines in a safe environment," says Dr. Mahan. "We’ll be there to help you stay comfortable every step of the way."

During this period, you’ll be on a liquid diet to help your body heal. Stick to clear liquids like water, broth and sugar-free drinks. Avoid carbonated drinks and anything with sugar.

Week 1: Light activity & soft foods

By the end of the first week, you should start feeling a bit better.

Dr. Mahan recommends, "Gradually increase your activity level, but avoid any strenuous exercise. Light walking is great for circulation and can help prevent blood clots."

You'll also transition to a soft diet, which includes foods that are easy to digest, such as mashed potatoes, scrambled eggs and pureed fruits and vegetables. Avoid anything that's hard, crunchy or high in fiber.

Weeks 2–4: Return to work & introduce solids

By the second week, you should be feeling more like yourself. Dr. Mahan notes, "Most patients can return to work around this time, but it depends on the nature of their job. If your job is physically demanding, you may need to wait 4 to 6 weeks."

During this period, you'll continue to follow a soft diet and gradually introduce more solid foods. It's important to eat slowly and chew your food thoroughly to avoid discomfort.

Avoid weight loss surgery complications

Follow these doctor-approved tips to avoid post-surgery complications and get back on your feet in no time.

Follow your doctor's advice: Your medical team will provide you with a detailed recovery plan. Stick to it to have the best possible outcome.
Stay hydrated: Drink plenty of water throughout the day to stay hydrated and aid in digestion.
Eat small, frequent meals: Instead of 3 large meals, opt for smaller, more frequent meals to avoid overwhelming your new, smaller stomach. This will also help you avoid complications like dumping syndrome.
Stay active: Light exercise, like walking, can help with recovery and boost your mood.
Manage stress: Stress can affect your recovery. Build up your personal stress relief toolkit and practice relaxation techniques like deep breathing, meditation or gentle yoga.
Lean on your care team: Your bariatric care team is available to answer any questions or concerns you have. When in doubt, reach out to them for help!

Returning to work after bariatric surgery

Returning to work is a significant milestone in your recovery. Dr. Mahan advises:

Desk or non-physical jobs: Return in about 2 – 4 weeks.
Physically demanding jobs: Wait 4 – 6 weeks before returning.

When you do return to work, take it easy. Don't overexert yourself and take breaks as needed. If you're feeling fatigued, it's okay to take a day off to rest.

Staying positive and motivated

Recovery from bariatric surgery is a journey, so it's important to build a support system to help you stay positive and motivated for the ups and downs.

Dr. Mahan emphasizes, "Celebrate your small victories along the way. Each step forward is a step toward a healthier you."

Joining a support group can also be incredibly helpful. Connecting with others who’ve gone through the same experience can provide emotional support and practical advice.

Bouncing back after weight loss surgery is a process, but with the right mindset and support, you can do it. Remember to take it one day at a time, follow your doctor's advice and be kind to yourself. You're on your way to a healthier, happier you!

Dr. Mahan’s last piece of advice: “If you have any questions or concerns during your recovery, reach out to your care team. We are cheering you on every step of the way!”
