How do I get rid of the gas in my chest after I had my surgery?

Gas pain in the chest after bariatric surgery is a common and often temporary discomfort, especially in the early postoperative period. It typically results from the gas used during laparoscopic surgery to inflate the abdomen, or from swallowed air and changes in digestion following the procedure. This gas can become trapped and rise, sometimes causing pressure or discomfort in the chest or shoulders, which can be alarming but is usually not dangerous.
To help relieve this discomfort, the first and most important thing is gentle movement. Walking frequently, even short distances around your home or hospital room, encourages your body to absorb and expel the gas more naturally. This also helps prevent other complications like blood clots. In addition to walking, focusing on deep breathing and changing positions can assist in releasing trapped air.
If you're experiencing gas due to swallowing air—something that can happen when sipping fluids too quickly or talking while eating—it helps to slow down. Take small, deliberate sips, avoid using straws, and try not to talk while eating or drinking. Staying upright after meals for at least 30 minutes also supports digestion and helps reduce gas buildup.
Simethicone, an over-the-counter anti-gas medication, may be recommended by your surgeon to break down gas bubbles in the stomach and intestines. However, it's important to speak with your surgical team before taking anything new to ensure it's safe based on your procedure and recovery status.
If the gas pain becomes severe, persists, or is accompanied by shortness of breath, fever, or rapid heart rate, it’s critical to contact your surgeon right away to rule out more serious complications like a leak or pulmonary issue.
Remember, your body is adjusting after major surgery, and while gas pain can be uncomfortable, it usually improves with time, movement, and attention to how you’re eating and drinking.

A key element of Gastric Sleeve Surgery is the use of CO2 to “inflate” your abdominal cavity in order to have room to comfortably perform the procedure, but after surgery is over, there’s some remaining CO2 inside.
There are two main methods of getting rid of the gas: 
1. Walking: When a patient walks, it helps to move the gas and to dissipate it quicker out of their body and reduce the bloated sensation they have.
2. Spirometer: The inhaled air helps expands the lungs. This reduces space in the chest causing the gas to be pushed out.

Hello, I'm sorry you are having a hard time, this is very common after surgery and in this early stage, the best recommendation is to contact the doctor who perform the procedure or contact your primary doctor, it's for your best if the doctor to prescribe any medication for the gases. You can also try walking, take small sips of water, take your time with the intake of liquids, chew your food at least 30 times. 
My Best Wishes,
