What is Inflammation? Everything You Really Need to Know

What is Inflammation

What is Inflammation?

When a wound occurs, the body’s response is to send immune cells to the area to fight infection and begin the healing process.

This is known as inflammation.

Inflammation is characterized by redness, swelling, and pain.

There are two types of inflammation: acute and chronic.

Acute inflammation is the body’s initial response to infection or injury and is usually short-lived.

Chronic inflammation occurs when the initial inflammatory response does not resolve and the inflammatory response continues.

In most cases, chronic inflammation can last for months or years and can lead to tissue damage. (1, 2, 3)

Causes of inflammation

There are many different causes of inflammation, but the most common cause is infection.

Infection occurs when viruses, bacteria, or other microorganisms enter the body and begin to multiply.

The body responds to these invading microorganisms by sending immune cells to the affected area.

The immune cells release chemicals that cause inflammation.

Other causes of inflammation include:

  • Allergies
  • Autoimmune diseases (eg, rheumatoid arthritis, Type 1 diabetes, lupus, psoriasis, celiac disease, multiple sclerosis (MS))
  • Environmental factors (eg, pollution, UV radiation)
  • Physical injury
  • Cancer
  • Certain medications
  • Physical inactivity
  • Obesity
  • Poor diet
  • Stress

Symptoms of acute Inflammation

Acute inflammation is generally caused by injury, insect bite, or infection.

For the most part, acute inflammation is a good thing.

Without it, wounds would not heal and infections would quickly spread throughout the body.

However, the most common symptom of acute inflammation is pain and tenderness at the site of injury

Other symptoms include:

  • Redness
  • Swelling
  • Stiffness
  • Loss of mobility
  • Heat at the site of injury

On the other hand, the symptoms of acute inflammation that are associated with infections are usually:

  • Fever
  • Chills
  • Body aches
  • Headaches
  • Fatigue
  • Loss of appetite
  • Nausea
  • Vomiting
  • Sleepiness

Symptoms of chronic inflammation

Chronic inflammation symptoms can vary depending on the individual.

However, there are some common symptoms that many people experience.

These can include:

If you are experiencing any of these symptoms on a regular basis, it is important to speak with your doctor.

They will be able to determine if you are suffering from chronic inflammation and develop a treatment plan that is right for you. (4, 5, 6)

What happens when there is inflammation?

The inflammatory response is a complex process that involves many different cells and proteins.

When inflammation occurs, these cells and proteins work together to remove the cause of inflammation and begin the healing process.

However, if the inflammatory response is not properly regulated, it can lead to tissue damage and disease.

For example, chronic inflammation has been linked to a number of diseases, including:

Treatment for inflammation

The treatment for inflammation depends on the underlying cause.

For example, if the inflammation is caused by an infection, the treatment will focus on clearing the infection.

If the inflammation is caused by an autoimmune disease, the treatment will focus on managing the disease.

There are many different options for treating inflammation, and the best approach depends on the individual.

Some common treatments include:

  • Anti-inflammatory medications (eg, ibuprofen, aspirin, naproxen)
  • Corticosteroids (eg, prednisone)
  • Immunosuppressive medications (eg, methotrexate, cyclosporine)
  • Disease-modifying antirheumatic drugs (DMARDs)
  • Biologic agents (eg, adalimumab, infliximab)
  • Diabetes medications
  • Surgery (eg, joint replacement surgery for RA)
  • Physical therapy
  • Heat or cold therapy
  • Lifestyle changes (eg, diet, exercise, stress reduction)

If you are suffering from inflammation, it is important to speak with your doctor about the best treatment approach for you.

Preventing inflammation

There are many things that you can do to prevent inflammation.

Some simple lifestyle changes that can help to reduce your risk of inflammation include:

  • Eating a healthy diet: A diet that is rich in fruits, vegetables, whole grains, and healthy fats can help to reduce inflammation.
  • Avoiding processed foods: Processed foods are high in sugar, unhealthy fats, and additives that can contribute to inflammation.
  • Exercising regularly: Exercise can help to reduce inflammation by improving circulation and reducing stress levels.
  • Staying hydrated: Proper hydration is essential for maintaining a healthy body and preventing inflammation.
  • Quitting smoking: Smoking is a major risk factor for inflammation and many other diseases.
  • Limiting alcohol consumption: Excessive alcohol consumption can lead to inflammation.
  • Avoiding exposure to environmental toxins: Exposure to toxins such as air pollution and chemicals can contribute to inflammation.
  • Managing stress: Stress can trigger the release of inflammatory mediators.
  • Getting enough sleep: Sleep is important for overall health and can help to reduce inflammation.


Inflammation is a reaction of the body to injury or infection. It is a natural process that helps the body heal and protects itself.

However, sometimes inflammation can become chronic and lead to health problems.

The treatment for inflammation depends on the underlying cause.

There are many things that you can do to prevent inflammation, including eating a healthy diet, exercising regularly, and staying hydrated.

If you are experiencing inflammation, speak with your doctor about the most effective treatment options for you.
