Chronic Inflammation — Notes (Based on the Document)

What is Chronic Inflammation?

Chronic inflammation is a prolonged inflammatory response — it can last weeks, months, or even years. It means the body keeps sending inflammatory cells without real cause, even when there's no actual danger present.

In simple words: The same process that normally protects the body (like in acute inflammation) ends up harming the body when it becomes chronic.

It can happen in two ways:

• Following acute inflammation — if the harmful agent isn't fully cleared
• Starting from scratch as chronic — without any acute phase (e.g., in TB, autoimmune diseases)
  

  Acute vs Chronic — Key Differences

  Point	Acute	Chronic
  Duration	Hours to days	Months to years
  Cells	Neutrophils	Macrophages, lymphocytes, plasma cells
  Function	Immediate response	Injury and healing occur together

  Features of Chronic Inflammation

  1. Infiltration by mononuclear cells — Macrophages, lymphocytes, and plasma cells collect at the site (instead of neutrophils)
  2. Tissue destruction — Caused by both the persistent injury and the inflammatory cells themselves
  3. Healing attempts — Angiogenesis (formation of new blood vessels) and fibrosis (scar tissue formation) happen alongside injury
  4. Injury and repair occur simultaneously — Both processes happen at the same time, not after another
  5. Granuloma formation (in some cases) — Macrophages cluster together to "wall off" something the body can't destroy
  6. Systemic symptoms — Fever, weight changes, fatigue, joint pain, mood issues may also occur (due to cytokines)

  Symptoms (According to the Document)

  Chronic inflammation symptoms are harder to spot because they're quite general:

  • Abdominal (belly) pain
  • Chest pain
  • Fatigue/insomnia
  • Fever
  • Joint pain or stiffness
  • Mouth sores
  • Skin rash
  • Depression, anxiety
  • GI issues (diarrhea, constipation, acid reflux)
  • Weight gain or weight loss
  • Frequent infections

  Conditions Associated with Chronic Inflammation

  • Autoimmune diseases — Lupus, Rheumatoid arthritis, Psoriasis, Ankylosing spondylitis
  • Cardiovascular diseases — Heart disease, high blood pressure
  • Certain cancers
  • GI diseases — Crohn's disease, IBD
  • Lung diseases — Asthma, COPD
  • Mental health conditions — Depression, anxiety
  • Metabolic diseases — Type 2 diabetes
  • Neurodegenerative diseases — Alzheimer's, Parkinson's

  Interesting fact: Inflammatory diseases account for more than half of all deaths globally.

  Causes of Chronic Inflammation.

  Treatment/Management

  • Rest, ice/cold pack, wound care (for acute inflammation)
  • Supplements — Zinc, certain vitamins, omega-3 (consult your provider first)
  • NSAIDs — Ibuprofen, aspirin, naproxen (don't use for more than 10 consecutive days without consulting a doctor)
  • Corticosteroids — Injection or oral medication (like prednisone) — used for RA, lupus, vasculitis

  Anti-inflammatory foods: Fatty fish (salmon), fresh fruits, leafy greens, turmeric, ginger, garlic — Mediterranean or DASH diet can help.

  Foods that cause inflammation: Trans fat foods, fried foods, cured/processed meats, high-salt foods, refined carbs (sugar, white bread)

  Prevention Tips

  • Aim for 150 minutes of moderate exercise per week
  • Avoid smoking/tobacco
  • Eat fresh, minimally processed food
  • Maintain a healthy weight
  • Limit alcohol intake
  • Reduce exposure to toxins/chemicals
