Complex Chronic Conditions

Mast Cell Activation Syndrome (MCAS) is a condition where mast cells—part of the immune system—inappropriately release excessive amounts of chemical mediators like histamine, leukotrienes, and cytokines. This causes systemic, allergic-like symptoms across multiple organ systems, often without a clear allergic trigger.

Postural Orthostatic Tachycardia Syndrome (POTS) is a form of dysautonomia characterized by an abnormal increase in heart rate (tachycardia) that occurs after sitting or standing up. It affects the autonomic nervous system's ability to regulate blood flow, leading to reduced blood return to the heart when upright.

Hypermobile Ehlers-Danlos Syndrome (hEDS) is a heritable connective tissue disorder characterized by generalized joint hypermobility, skin hyperextensibility, and tissue fragility. Connective tissue is the 'glue' of the body, so defects can lead to widespread multi-systemic issues. The EDS community often identifies as 'zebras', as medical students are taught 'when you hear hoofbeats, think horses, not zebras'—but sometimes, it really is a zebra.

Mold Toxicity, often presenting as Chronic Inflammatory Response Syndrome (CIRS), occurs when susceptible individuals are exposed to biotoxins from water-damaged buildings. Their immune systems fail to clear these mycotoxins, leading to a state of chronic, systemic inflammation.

Long COVID, or Post-Acute Sequelae of SARS-CoV-2 infection (PASC), refers to a range of new, returning, or ongoing health problems people can experience four or more weeks after first being infected with the virus that causes COVID-19. It shares many clinical similarities with ME/CFS and dysautonomia.

Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted through the bite of infected ticks. When not treated early or adequately, it can become chronic or late-stage, causing severe multi-systemic issues. Ticks often transmit other pathogens simultaneously, known as co-infections (e.g., Babesia, Bartonella).

Dysautonomia is an umbrella term used to describe several different medical conditions that cause a malfunction of the Autonomic Nervous System (ANS). The ANS controls the 'automatic' functions of the body that we do not consciously think about, such as heart rate, blood pressure, digestion, dilation and constriction of the pupils of the eye, kidney function, and temperature control.

Fibromyalgia is a disorder characterized by widespread musculoskeletal pain accompanied by fatigue, sleep, memory, and mood issues. Researchers believe that fibromyalgia amplifies painful sensations by affecting the way your brain and spinal cord process painful and nonpainful signals (central sensitization).

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a complex, chronic, debilitating disease characterized by profound fatigue, cognitive dysfunction, sleep abnormalities, autonomic manifestations, pain, and other symptoms that are made worse by exertion of any sort (Post-Exertional Malaise).

Endometriosis is a disease in which tissue similar to the lining of the uterus grows outside the uterus. It can cause severe pain in the pelvis and make it harder to get pregnant. It is increasingly recognized as a systemic, whole-body inflammatory disease rather than just a reproductive issue.

Hashimoto's thyroiditis is an autoimmune disorder in which the immune system mistakenly attacks the thyroid gland, leading to chronic inflammation and often resulting in an underactive thyroid (hypothyroidism). It is the most common cause of hypothyroidism in the United States.

Genetic conditions and biochemical sensitivities involve inheritable genetic variations (SNPs) like MTHFR, COMT, and others that affect methylation, detoxification, and histamine breakdown. These genetic terrains can predispose individuals to chronic illness, Mast Cell Activation Syndrome (MCAS), hypermobility (hEDS), and hyper-reactivity to environmental triggers.

Autoimmune conditions occur when the immune system mistakenly attacks the body's own tissues. While there are many specific diagnoses (such as Rheumatoid Arthritis, Multiple Sclerosis, Lupus, etc.), functional medicine approaches them by looking at the underlying immune dysregulation, gut health, and environmental triggers that are common across the autoimmune spectrum.

Early Alzheimer's and cognitive decline are increasingly viewed in functional medicine as a result of multiple metabolic, toxic, and inflammatory insults to the brain, rather than just a single disease process. Addressing these root causes early can often halt or reverse cognitive decline.
