Mast cell activation syndrome causes symptoms in nearly every organ system, from flushing and hives to brain fog and anaphylaxis. Here is how to recognize the pattern.
Hashimoto's thyroiditis is an autoimmune attack on the thyroid and the most common cause of hypothyroidism in the US. It is diagnosed with TSH, free T4 and thyroid antibody tests, treated with thyroid hormone when levels fall, and monitored for life.
A thorough guide to multiple sclerosis covering types, symptoms, diagnosis, disease-modifying therapies, integrative approaches, and practical strategies for living well with MS.
Ehlers-Danlos syndrome (EDS) is a group of 13 inherited collagen disorders. Hypermobile EDS, the most common type, has no known gene and is diagnosed clinically with the 2017 criteria; care centers on stability-focused physical therapy and treating overlaps such as POTS and MCAS.
MCAS and POTS co-occur at high rates because mast cell mediators affect blood vessel tone and heart rate. Learn the diagnostic overlap, the triad with EDS, and coordinated treatment.
MCAS happens when mast cells release histamine and other mediators too often or in response to harmless triggers, causing symptoms across the skin, gut, heart, lungs, and brain.
EDS is diagnosed with the 2017 international criteria: hypermobile EDS needs an age-adjusted Beighton score, two of three feature groups and exclusion of other conditions, while the other 12 subtypes are confirmed by genetic testing.
Chronic inflammation is a low-grade immune response that stays on for months or years. Learn its main causes, the symptoms it produces, how the hs-CRP test measures it, and which diet, sleep and lifestyle changes lower it.
The most common autoimmune disease symptoms are fatigue, joint pain with morning stiffness, rashes, brain fog and digestive problems. Learn the common types, the tests that confirm them and who treats them.
Histamine intolerance happens when histamine from food and the body builds up faster than the gut enzyme DAO can break it down, causing flushing, headaches, bloating and other symptoms. Learn the triggers, how it is tested, the low-histamine diet and who treats it.
Hashimoto's thyroiditis often hides behind a normal TSH, because TSH tracks hormone output rather than the immune attack. TPO antibodies can appear up to 7 years before diagnosis, so a full panel with antibodies gives a clearer answer.
