Bloating occurs when the abdomen fills with air or gas. This can make your abdomen appear larger and feel tight or hard to the touch. It can also cause feelings of discomfort and pain, which may be felt toward your back.
The back acts as a support and stabilizing system for your body. It’s vulnerable to injury and strain, so it’s not uncommon to feel back pain along with abdominal bloating. The pain can vary in severity and type, from sharp and stabbing to dull and aching.

Causes of abdominal bloating
Abdominal bloating is commonly caused by gas and air in the gastrointestinal tract. When your body breaks down undigested food, gas builds up in the digestive tract (from the esophagus to the large intestine). You can also swallow air. It’s possible to swallow more air than normal by:
- eating or drinking too quickly
- chewing gum
- wearing loose dentures
Burping and flatulence are two ways swallowed air leaves the body. Delayed emptying of the stomach (slow gas transport) in addition to gas accumulation can also cause bloating and abdominal distension.
Abdominal bloating and back pain typically resolve with time. If your abdominal bloating and back pain persist, make an appointment with your doctor. You may need medical attention if your symptoms are caused by infection or other severe or chronic illness.
These conditions may include:
See your doctor
Seek immediate medical attention if:
- you are pregnant
- your abdominal bloating and back pain are more intense than before
- over-the-counter (OTC) pain medications or heat or ice packs do not provide relief
- bloating and pain impact daily functioning
- You should also seek immediate attention if you have any of the following symptoms:
- blood in your stool
- chest pain
- difficulty breathing
- loss of consciousness
- uncontrolled vomiting
- fever or chills
- Make an appointment with your doctor if you experience any of the following symptoms for more than 24 hours:
- stomach acid reflux
- blood in your urine
- itchy, blistery rash
- painful urination
- increased urinary frequency or urgency
- unexplained fatigue
Treatments for abdominal bloating and back pain depend upon the cause of your symptoms. Your doctor may recommend basic blood tests or imaging to find the cause of your symptoms before recommending treatment.
Most of the time abdominal bloating and back pain will resolve itself, but there are steps you can take at home to manage any discomfort.
To reduce bloating:
- Drink plenty of water or other clear fluids.
- Take over-the-counter (OTC) gas or acid-reducing medications, such as antacids, simethicone drops, or digestive enzymes.
- Drink fewer carbonated drinks and reduce use of straws.
- Avoid foods that cause gas, such as dried beans, whole grains, and lentils.
- If you have a food intolerance, avoid eating or drinking those foods.
Treatments for back pain:
- Applying ice packs and heat packs alternately for 10 minutes at a time may help to relieve back pain and discomfort. Resting your back and refraining from heavy lifting can also minimize painful symptoms.
- Massages work as a complementary treatment for back pain. They may also provide extra relief for bloating.
- Exercise and good posture can help reduce back pain and may be beneficial for bloating as well.
- OTC pain relievers such as ibuprofen and acetaminophen may provide relief from back pain. However, there are risks with the overuse of these pain medications. Ask a doctor about other ways to manage if you need to take them for a prolonged period.
In addition to avoiding foods known to cause abdominal bloating, there are other lifestyle changes that can prevent symptoms. These include:
- drinking plenty of water, which helps to reduce constipation
- eating a diet that contains high-fiber foods that promote regularity, such as fruits, vegetables, and whole grains
- eating several small meals each day instead of fewer, larger ones
- exercising regularly
While you cannot always prevent back pain, employing proper lifting techniques and avoiding long periods of sitting can help you find some relief.
