Inflammation is a part of the body's defense mechanism. It is a process through which the immune system recognizes and fights against harmful infections and makes toxins to protect the body. However, long-term infection is not beneficial to the body. Chronic inflammation lasts for several months or years in response to the stimuli inside or outside the body. Chronic inflammation may persist even after the first trigger is gone.
The white blood cells accumulate in the body tissues and secrete chemicals that may eventually damage the tissues. The extent and effects of chronic inflammation depend on the cause of the injury and the body’s ability to repair and overcome the damage.
Risk factors of chronic inflammation
A range of factors may increase the risk of chronic inflammation, such as
- Older age
- Obesity
- Smoking
- Alcohol abuse
- Chronic stress
- Sleep problems
- Low sex hormones
- Diabetes mellites
- Diet rich in unhealthy fats and added sugar
- Foods that trigger inflammation
The intake of the following foods can increase inflammation. Limit or avoid their consumption.
- Refined carbohydrates, such as white bread, pasta and pastries
- Fried foods
- Highly processed foods
- Red meat
- Processed meat, such as hot dogs and sausage
- Soda and fruit juices with added sugars
- Unhealthy fats, such as saturated and trans fats
Complications of chronic inflammation
When a person has chronic inflammation, the body’s inflammatory response can eventually start damaging healthy cells, tissues and organs. Over time, this can damage DNA, cause tissue death and thicken and scar tissues.
Chronic inflammation may increase the risk of several serious diseases, including
- Cancers
- Atherosclerosis
- Cardiovascular disease
- Chronic obstructive pulmonary disease
- Psoriasis
- Periodontitis
- Ulcerative colitis and Crohn’s disease
- Active hepatitis

Asthma
Asthma is a condition in which hyperreactive airways constrict and result in symptoms like wheezing, coughing, and shortness of breath. Causes of asthma include genetics, environmental factors, personal history of allergies, and other factors. Asthma is diagnosed by a physician based on a patient's family history and results from lung function tests and other exams. Inhaled corticosteroids (ICS) and long-acting bronchodilators (LABAs) are used in the treatment of asthma. Generally, the prognosis for a patient with asthma is good. Exposure to allergens found on farms may protect against asthma symptoms.COPD vs. Asthma (Differences and Similarities)
COPD (chronic obstructive pulmonary disease) and asthma both have common symptoms like coughing, wheezing, shortness of breath, and a tight feeling in the chest. COPD is caused by tobacco smoking, while asthma is caused by your inherited genetic makeup and their interactions with the environment. Risk factors for asthma are obesity, exposure to cigarette smoke (even secondhand smoke), and personal history of hay fever.

Hepatitis is most often viral, due to infection with one of the hepatitis viruses (A, B, C, D, E, F (not confirmed), and G) or another virus (such as those that cause infectious mononucleosis, cytomegalovirus disease). The main nonviral causes of hepatitis are alcohol and drugs. Many patients infected with hepatitis A, B, and C have few or no symptoms of illness.
