Inflammation is the body’s natural response to irritation, injury, or infection.
When inflammation happens, your immune system sends blood flow and healing cells to an area to protect it and help it recover. Inflammation can be short-term or long-lasting, depending on the cause.
Inflammation is a process, not a diagnosis.
Doctors most often use inflammation to describe:
Infection, such as a virus or bacteria
Injury or strain, including muscle or joint stress
Autoimmune activity, where the immune system is overactive
Chronic conditions, such as arthritis
Lifestyle factors, including stress, diet, or lack of sleep
Inflammation is common and often part of healing.
Inflammation may cause symptoms such as:
Swelling
Redness or warmth
Stiffness
Symptoms depend on where inflammation occurs in the body.
Inflammation in muscles or joints can build up overnight, leading to stiffness or soreness in the morning.
Inflammation can flare due to activity, stress, weather changes, or underlying conditions, causing symptoms to vary.
Inflammation can affect energy levels and sleep quality, which may lead to fatigue.
Some blood tests look for markers that rise when inflammation is present somewhere in the body.
Doctors may check inflammation using:
Blood tests that measure inflammation markers
Physical exams
Imaging such as X-rays or MRI (if needed)
Review of symptoms over time
Testing helps identify patterns, not just one reading.
Many cases of inflammation are managed by a primary care doctor.
Rheumatologist – for joint or autoimmune inflammation
Gastroenterologist – for digestive inflammation
Pulmonologist – for lung-related inflammation
Specialist care depends on the location and cause.
For many people, next steps may include:
Treating the underlying cause
Short-term medications to reduce inflammation
Lifestyle adjustments
Monitoring symptoms over time
Inflammation often improves once the trigger is addressed.
