What is inflammation?
Inflammation refers to your body’s process of fighting against things that harm it, such as infections, injuries, and toxins, in an attempt to heal itself. When something damages your cells, your body releases chemicals that trigger a response from your immune system.
This response includes the release of antibodies and proteins, as well as increased blood flow to the damaged area. The whole process usually lasts for a few hours or days in the case of acute inflammation.
Chronic inflammation happens when this response lingers, leaving your body in a constant state of alert. Over time, chronic inflammation may have a negative impact on your tissues and organs. Some

Acute inflammation often causes noticeable symptoms, such as pain, redness, or swelling. But chronic inflammation symptoms are usually subtler. This makes them easy to overlook.
Common symptoms of chronic inflammation include:
- mouth sores
- abdominal pain
- chest pain
These symptoms can range from mild to severe and last for several months or years.
Several things can cause chronic inflammation, including:
- untreated causes of acute inflammation, such as an infection or injury
- an autoimmune disorder, which involves your immune system mistakenly attacking healthy tissue
- long-term exposure to irritants, such as industrial chemicals or polluted air
Keep in mind that these don’t cause chronic inflammation in everyone. In addition, some cases of chronic inflammation don’t have a clear underlying cause.
Experts also believe that a range of factors may also contribute to chronic inflammation, such as:
When you have chronic inflammation, your body’s inflammatory response can eventually start damaging healthy cells, tissues, and organs. Over time, this can lead to DNA damage, tissue death, and internal scarring.

Inflammation is a natural part of the healing process. But when it becomes chronic, it’s important to get it under control to reduce your risk of long-term damage. Some of the options that have been explored for managing inflammation include:
- Nonsteroidal anti-inflammatory drugs (NSAIDs). Over-the-counter NSAIDs, such as aspirin, ibuprofen (Advil), and naproxen (Aleve), effectively reduce inflammation and pain. But long-term use is
linkedto an increased risk of several conditions, including peptic ulcer disease and kidney disease.
- Steroids. Corticosteroids are a type of steroid hormone. They decrease inflammation and suppress the immune system, which is helpful when it starts attacking healthy tissue. But long-term use of corticosteroids can lead to vision problems, high blood pressure, and osteoporosis. When prescribing corticosteroids, your doctor will weigh the benefits and risks with you.
- Supplements. Certain supplements may help to reduce inflammation.
Fish oil, lipoic acid, and curcumin are all linked to decreases inflammation associated with diseases, including cancer and heart disease. Several spices may also help with chronic inflammation and inflammatory disease, including ginger, garlic, and cayenne. Learn more about spices that fight inflammation.
What you eat can play both a positive and negative role in managing chronic inflammation.
