Inflammation: Symptoms, Possible Causes, and Treatment
Inflammation is the result of the body protecting itself from infection and healing itself after injury.
Everyone needs inflammation in their bodies. However, when inflammation lingers for too long or if levels of it are too high, inflammation can be dangerous, according to the Department of Veterans Affairs (VA). It may contribute Alzheimer’s disease, cancer, asthma, and autoimmune diseases.
If you have ongoing inflammation, medication and certain lifestyle practices can help reduce it and prevent inflammatory diseases.
This article will discuss the symptoms and causes of acute and chronic inflammation, how doctors diagnose inflammation, and tips on reducing inflammation.
Inflammation is usually a natural process that helps the body heal from injuries or infections. Blood flows to the damaged tissue, which supplies essential blood cells and proteins to remove any byproducts or debris. This blood flow naturally causes the area to become swollen, red, warm to the touch, and painful. Your body needs inflammation to heal.
Acute inflammation sends white blood cells to the affected area. This fast response allows your body to heal from injuries and prevent damage from infections. Acute inflammation occurs relatively quickly and may last a few days.
Experts consider subacute inflammation a condition in which acute inflammation begins evolving into chronic inflammation. This period lasts 2–6 weeks.
Chronic inflammation is when your white blood cells react as though the body is constantly injured and trying to heal. You have too much inflammation, or the inflammation remains in your body for too long. Chronic inflammation can last for months or years.
Signs and symptoms can vary between acute and chronic inflammation.
Signs and symptoms of acute inflammation may develop suddenly and include:
- discoloring of the area, such as the skin
Chronic inflammation symptoms, which can take longer to develop and involve many areas of the body, include:
- weight gain
- muscle aches
- joint pain
- Environmental: Pollutants, such as air pollution, asbestos, smoking, and other toxic chemicals, can cause inflammation.
- Nutritional: Diets high in white bread, pasta, sugary drinks, red meats, fried foods, or alcohol can change your gut health and affect your immune system.
- Lifestyle and physical: Irregular sleep patterns and lack of exercise can lead to inflammation.
- Health: Certain conditions, such as infection, obesity, and stress, can lead to inflammation.
If your doctor thinks your symptoms are due to a chronic inflammatory process, they can conduct a blood test to look for certain cells or proteins in your bloodstream. The blood tests are not specific and cannot reveal whether you have acute or chronic inflammation. Your doctor may need to carry out other tests to determine the exact cause of your symptoms.
Blood tests that help detect inflammation include:
- C-reactive protein (CRP)
- erythrocyte sedimentation rate
- white blood cell count
Depending on your symptoms, your doctor may request other tests. If your doctor suspects you may have inflammation in your large intestine, they may request an imaging test, such as a colonoscopy. If your doctor thinks you may have inflammation in your brain, they may request an MRI.
Treatment for inflammation depends on what is causing it. Medications, diet, and self-care can help reduce or reverse inflammation. The specific regimen may differ for acute versus chronic inflammation.
Doctors may prescribe medications to help reduce inflammation and symptoms when you have chronic inflammation. These may help with certain conditions, such as rheumatoid arthritis and inflammatory bowel disease, and may include:
- nonsteroidal anti-inflammatory drugs (NSAIDs)
- biologic drugs that change the way the immune system works and are

Diet and nutrition tips
Certain foods can cause inflammation, and other foods can reduce and even prevent inflammation.
To reduce your likelihood of getting inflammation, limit or stop eating foods such as:

- pastries and cakes
- red meats
- sugary drinks

How can you reduce inflammation in the body fast?
Taking NSAIDs, such as ibuprofen (Advil, Motrin), can reduce pain quickly, even within a few hours for arthritis. However, you may need prescription-strength NSAIDs to reduce inflammation. Your doctor may prescribe corticosteroids and stronger anti-inflammatories that are not available over the counter. Talk with your doctor about your diagnosis and treatment plan to reduce inflammation quickly.

Inflammation is the body’s way of protecting itself from injury or disease. Acute inflammation is helpful. Chronic inflammation can lead to disease. The treatment and outcome of inflammation depend on the cause or source.
