Inflammation

Inflammation (from Latin: inflammatio) is part of the biological defence response of body tissues. Inflammatory immunovascular responses can be triggered by a broad range of stimuli, including physical trauma, "dead, damaged, malfunctioning or stressed tissues", pathogens, irritants, toxins, overuse, autoimmunity, allergens, and foreign bodies (e.g. silica and asbestos). The five cardinal signs are heat, pain, redness, swelling, and loss of function (Latin calor, dolor, rubor, tumor, and functio laesa). Inflammation is a generic response, and therefore is considered a mechanism of innate immunity, not adaptive immunity. It involves immune cells, blood vessels, and molecular mediators. The function of inflammation is to eliminate the initial cause of cell injury, clear out damaged cells and tissues, and initiate tissue repair. Too little inflammation could lead to progressive tissue destruction by the harmful stimulus (e.g. bacteria) and compromise the survival of the organism. However, inflammation can also have negative effects. For instance, too much inflammation, in the form of chronic inflammation, is associated with various diseases, such as hay fever, periodontal disease, atherosclerosis, and osteoarthritis. Inflammation can be classified as acute or chronic. Acute inflammation is the initial response of the body to harmful stimuli, and is achieved by the increased movement of plasma and leukocytes (in particular granulocytes) from the blood into the injured tissues. A series of biochemical events propagates and matures the inflammatory response, involving the local vascular system, the immune system, and various cells in the injured tissue. Prolonged inflammation, known as chronic inflammation, leads to a progressive shift in the type of cells present at the site of inflammation, such as mononuclear cells, and involves simultaneous destruction and healing of the tissue. Inflammation has also been classified as Type 1 and Type 2 based on the type of cytokines and helper T cells (Th1 and Th2) involved.

  ## Inflammation Treatment Treatment for diseases that cause chronic inflammation may include medications, rest, exercise, and surgery to correct joint damage. Your treatment plan will depend on several things, including your type of disease, your age, the medications you’re taking, your overall health, and how severe the symptoms are. The goals of treatment are to: Correct, control, or slow down the disease process Avoid or change activities that aggravate pain Ease pain through pain medications and anti-inflammatory drugs Keep joint movement and muscle strength through physical therapy Lower stress on joints by using braces, splints, or canes as needed Medications for inflammation [...] ## Takeaways Inflammation is your body's response to an injury or illness, or to the perception of one. When it's acute, you might have redness and swelling for a few days as your body activates white blood cells to combat the problem. Chronic inflammation can last months or years. In some cases, your immune system is misfiring and attacking healthy parts of your body. You might need medicine or surgery to relieve your symptoms. You can take steps at home, including quitting tobacco, reducing alcohol consumption, getting moderate exercise, and eating a diet rich in anti-inflammatory foods. ## Inflammation FAQs Can I reduce inflammation in my body quickly? For acute inflammation, you can: [...] ## Inflammation Types Acute inflammation This type is short-lived and goes away within hours or days. It's a response to an illness or injury. Your body sends inflammatory cells to the site of the problem so you can start recovering. Examples of things that can trigger acute inflammation include: Cuts Viral illnesses such as the flu Bacterial infections such as strep throat Chronic inflammation

• What is Inflammation? Causes, Effects, Treatment - Harvard Health

  Gastrointestinal tract. Inflammation is a driver of inflammatory bowel disease (IBD), a chronic inflammation of the gastrointestinal (GI) tract, including the stomach, gallbladder, and small and large intestines. Two types of IBD are ulcerative colitis, marked by continuous inflammation of the large intestine, and Crohn's disease, which causes inflammation anywhere in the GI tract. People with IBD can experience various symptoms such as abdominal pain, diarrhea, blood in their stool, bloating, and weight loss. [...] You've seen the effects of inflammation in real time if you've ever gotten a paper cut, sprained your ankle, or been stung by a bee. Redness and heat, along with pain and swelling that result from an injury or infection, are evidence of the inflammatory process underway beneath the skin's surface. Not visible but similar in process is the inflammation that results when you come down with an infection like the flu or pneumonia. In both cases, the immune system is waging a battle inside your body against invading microbes. Without its defenses, a minor cut or illness could quickly turn deadly. There are two types of inflammation: acute and chronic. [...] It's also possible that diet can cause chronic inflammation. Research has shown that pro-inflammatory diets are associated with a higher risk of chronic diseases that are fueled by inflammation, such as heart disease and diabetes. High-inflammatory foods include red meat and processed meat, refined carbohydrates such as white bread, white rice, snack foods, desserts, and sweetened beverages like soft drinks. ## Where does inflammation occur? Chronic inflammation can attack the entire body and, in the process, raise the risk for certain types of diseases and disorders in specific areas like the heart, brain, joints, and gastrointestinal tract.

• What Causes Inflammation and How Does It Affect Our Health?

  There are two inflammation types: acute inflammation and chronic inflammation. Acute inflammation commonly occurs as the body’s natural defense against infection or injury. For example, if you come down with a cold or cut your finger, your body triggers an inflammatory response that directs immune cells to the injury site to start the healing process. Chronic inflammation, on the other hand, happens when inflammation occurs in healthy tissues or lasts too long — for months or sometimes years. This type of inflammation can lead to longer-term damage of previously healthy tissues and gradually inhibit the body’s ability to repair itself. ## Causes of Inflammation [...] ## Causes of Inflammation Every day, scientists are learning more about what causes inflammation in the body and its role in disease. We know, for example, that chronic inflammation") occurs in many diseases, including cancer, heart disease and Alzheimer’s disease. We also know that inflammation plays a role in organ failure, Type 2 diabetes and severe infectious diseases like COVID-19. The bottom line is that inflammation is present in many diseases and is a complicated process involving many different types of immune cells interacting with local tissue environments. [...] Inflammation has a layered impact on our biology, from the systemic effects on our whole body (like fever), right down to the target cells and tissues. The CZI Cell Science (formerly the Single-Cell Biology) team funds inflammation grants and brings together collaborations of researchers with a variety of expertise to develop tools to study inflammation at the cellular level. Using single-cell methods brings unprecedented technical resolution to a biologically complex process. This approach may help us better understand specific cells or groups of cells that contribute to inflammation in specific diseases or are common to many diseases.

  Cover of InformedHealth.org ## InformedHealth.org [Internet]. # In brief: What is an inflammation? Last Update: April 11, 2025; Next update: 2028. When a wound swells up, turns red and hurts, it may be a sign of inflammation. Very generally speaking, inflammation is the body’s immune system’s response to an irritant. The irritant might be a germ, but it could also be a foreign object, such as a splinter in your finger. This means that an inflammation doesn’t only start when, for instance, a wound has already been infected by bacteria, is oozing pus or healing poorly. It already starts when the body is trying to fight against the harmful irritant. ## What causes an inflammation? Many different things can cause inflammations. These are the most common: [...] Diseases or medical conditions that cause inflammation often have a name ending in “-itis.” For example: Cystitis: an inflammation of the bladder Bronchitis: an inflammation of the bronchi Otitis media: an inflammation of the middle ear Dermatitis: a disease where the skin is inflamed ## What are the signs of an inflammation? There are five symptoms that may be signs of an acute inflammation: Examples of a loss of function include not being able to move an inflamed joint properly, having a worse sense of smell during a cold, or finding it more difficult to breathe when you have bronchitis. Inflammations don’t always cause all five symptoms. Some inflammations occur “silently” and don’t cause any symptoms. ## What are the potential consequences of a severe inflammation? [...] ## What exactly does inflammation involve? When an inflammation occurs in your body, many different immune system cells may be involved. They release various substances, known as inflammatory mediators. These include the hormones bradykinin and histamine. They cause the small blood vessels in the tissue to become wider (dilate), allowing more blood to reach the injured tissue. For this reason, inflamed areas turn red and feel hot. The increased blood flow allows more immune system cells to be carried to the injured tissue, where they help with the healing process. What’s more, both of these hormones irritate nerves and cause pain signals to be sent to the brain. This has a protective function: If the inflammation hurts, you tend to protect the affected part of the body.

The Center for Inflammation Science and Systems Medicine Inflammation is a natural part of the body’s reaction to injury and infection, and is essential the body’s healing process. The term “inflammation” refers to the complex process by which the body’s innate immune system responds to harmful stimuli such as trauma, toxins and invading pathogens such as bacteria and viruses. [...] In survivors of ARDS as well as many individuals with chronic disorders, the dysregulated immune response can also lead to persistent inflammation (months to years) as a result of genetic predisposition and ongoing environmental exposures. Persistent inflammation increases the risk of developing autoimmune diseases such as metabolic syndrome, rheumatoid arthritis, diabetes, systemic lupus, inflammatory bowel disease asthma, and other serious disorders. The body’s response to persistent inflammation in a specific organ is the development of scar tissue or fibrosis, which can occur in the heart, lung, liver, kidneys or bowel and thereby reduce organ function. Chronic inflammatory diseases contribute to more than 50% of deaths worldwide.
