Inflammation: All You Should Know


Inflammation is the body’s attempt at self-protection to remove harmful stimuli and begin the healing process.

Infections, wounds, and any damage to tissue would not be able to heal without an inflammatory response.

Chronic inflammation can eventually cause several diseases and conditions, including some cancers and rheumatoid arthritis.

Signs Of Bad Inflammation:

Pain: The inflamed area is likely to be painful, especially during and after touching. Chemicals that stimulate nerve endings are released, making the area more sensitive.

Redness: This occurs because the capillaries in the area are filled with more blood than usual.

Immobility: There may be some loss of function in the region of the inflammation.

Swelling: This is caused by a buildup of fluid.

Heat: More blood flows to the affected area, and this makes it feel warm to the touch.

Note: These five acute signs only apply to that of the skin. If inflammation occurs deep inside the body, such as in an internal organ, only some of the signs may be noticeable.

For example, some internal organs may not have sensory nerve endings nearby, so there will be no pain, such as in certain types of lung inflammation.

However, symptoms of chronic inflammation present in a different way, and these can include:


mouth sores

chest pain

abdominal pain



joint pain

Thus, inflammations don’t always help the body,In some diseases the immune system fights against the body’s cells by mistake, causing harmful inflammations.


Many different things can cause inflammations. These are the most common:

Pathogens (germs) like bacteria,

viruses or fungi

External injuries like scrapes or damage through foreign objects (for example a thorn in your finger)

Effects of chemicals or radiation

Diseases or medical conditions that cause these conditions often have a name ending in “-itis.” For example:

  1. Cystitis: an inflammation of the bladder
  2. Bronchitis: an inflammation of the bronchi
  3. Otitis media: an inflammation of the middle ear
  4. Dermatitis: a disease where the skin is inflamed
What Happen When You Have Acute Inflammations

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.

Thus, the increased blood flow also 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.

Therefore, the inflammatory mediators have yet another function: They make it easier for immune system cells to pass out of the small blood vessels so that more of them can enter the affected tissue.
