Inflammation is part of the body’s defense mechanism and plays a role in the healing process. When the body detects an intruder, it launches a biological response to try to remove it.
The attacker could be a foreign body, such as a thorn, an irritant, or a pathogen. Pathogens include bacteria, viruses, and other organisms, which cause infections.
Sometimes, the body mistakenly perceives its own cells or tissues as harmful. This reaction can lead to autoimmune diseases, such as type 1 diabetes.
Experts believe inflammation may contribute to a wide range of chronic diseases. Examples of these are metabolic syndrome, which includes type 2 diabetes, heart disease, and obesity.
People with these conditions often have higher levels of inflammatory markers in their bodies.
In this article, find out more about why inflammation happens, its symptoms, and ways to resolve it.
A person with acute inflammation might experience pain in the affected area.
There are two main types of inflammation: acute and chronic.
An injury or illness can involve acute, or short-term, inflammation.
There are five key signs of acute inflammation:
These signs are not always present. Sometimes inflammation is “silent,” without symptoms. A person may also feel tired, generally unwell, and have a fever.
Chronic inflammation can continue for months or years. It either has or may have links to various diseases, such as:
The symptoms will depend on the disease, but they may include pain and fatigue.
When inflammation is present in the body, there will be higher levels of substances known as biomarkers.
An example of a biomarker is C-reactive protein (CRP). If a doctor wants to test for inflammation, they may assess CRP levels.
CRP levels tend to be higher in older people and those with conditions such as cancer and obesity. Even diet and exercise may make a difference.
Inflammation happens when a physical factor triggers an immune reaction. Inflammation does not necessarily mean that there is an infection, but an infection can cause inflammation.
Acute inflammation can result from:
When the body detects damage or pathogens, the immune system triggers a number of reactions:
Signs of acute inflammation can appear within hours or days, depending on the cause. In some cases, they can rapidly become severe. How they develop and how long they last will depend on the cause, which part of the body they affect, and individual factors.
Some factors and infections that can lead to acute inflammation include:
Chronic inflammation can develop if a person has:
Sensitivity: Inflammation happens when the body senses something that should not be there. Hypersensitivity to an external trigger can result in an allergy.
Exposure: Sometimes, long-term, low-level exposure to an irritant, such as an industrial chemical, can result in chronic inflammation.
Autoimmune disorders: The immune system mistakenly attacks normal healthy tissue, as in psoriasis.
Autoinflammatory diseases: A genetic factor affects the way the immune system works, as in Behçet’s disease.
Persistent acute inflammation: In some cases, a person may not fully recover from acute inflammation. Sometimes, this can lead to chronic inflammation.
Factors that may increase the risk of chronic inflammation include:
Long-term diseases that doctors associate with inflammation include:
Inflammation plays a vital role in healing, but chronic inflammation may increase the risk of various diseases, including some cancers, rheumatoid arthritis, atherosclerosis, periodontitis, and hay fever.
Acute inflammation can cause pain of varying types and severity. Pain may be constant and steady, throbbing and pulsating, stabbing, or pinching.
Pain results when the buildup of fluid leads to swelling, and the swollen tissues push against sensitive nerve endings.
Other biochemical processes also occur during inflammation. They affect how nerves behave, and this can contribute to pain.
Some foods contain nutrients that may help reduce inflammation.
They include:
Studies have suggested that people with high levels of CRP may be less likely to follow a diet that is rich in fresh products and healthy oils, such as the Mediterranean diet.
The following may aggravate inflammation:
Diet alone will not control inflammation, but making suitable choices may help prevent it from getting worse.
This remedy may be helpful for pain and inflammation that comes on suddenly after exposure to cold wind and weather. The person is likely to feel fearful, panicked, or agitated.
