Conditions of the body, organ systems, pain, and somatic illnesses linked to prolonged stress.

Cardiovascular and metabolic

– Hypertension (high blood pressure)

– Coronary artery disease / accelerated atherosclerosis

– Myocardial ischemia and increased risk of heart attack (stress as a trigger)

– Cardiac arrhythmias and palpitations (stress-induced)

– Stroke risk increased by chronic stress and acute stress events

– Metabolic syndrome (central obesity, dyslipidemia, glucose intolerance)

– Type 2 diabetes onset or poorer glycemic control

– Elevated resting heart rate and altered heart rate variability

Neuromusculoskeletal, pain syndromes, and somatic pain

– Tension-type headaches

– Migraines (frequency/intensity worsened by stress)

– Chronic daily headache

– Temporomandibular joint disorder (TMJ) and bruxism (teeth grinding)

– Cervical (neck) pain and stiffness

– Back pain (low back pain) and muscle spasm

– Myofascial pain syndrome

– Fibromyalgia (stress is a common precipitant and amplifier)

– Chronic widespread pain syndromes

– Sciatica and radicular pain flares related to muscle tension

– Joint pain exacerbations (arthritic pain flares linked to stress)

– Recurrent musculoskeletal injuries from muscle tension and poor recovery

Gastrointestinal and nutrition-related

– Irritable bowel syndrome (IBS) — diarrhea-predominant, constipation-predominant, mixed

– Functional dyspepsia and non-ulcer stomach pain

– Exacerbations of inflammatory bowel disease (Crohn’s disease, ulcerative colitis) (stress commonly triggers flares)

– Gastroesophageal reflux disease (GERD) symptoms worsened by stress

– Peptic ulcer disease symptoms may be aggravated by stress (H. pylori also key)

– Chronic constipation or chronic diarrhea from altered gut motility

– Nausea, early satiety, abdominal pain related to stress

– Unhealthy eating patterns leading to weight loss or gain, nutrient deficiencies

Immune, infectious disease, and inflammation

– Immunosuppression (increased susceptibility to infections; slower wound healing)

– Recurrent infections (respiratory, herpes simplex/reactivation of cold sores, shingles)

– Exacerbation of autoimmune diseases (e.g., rheumatoid arthritis, lupus, multiple sclerosis) during stress

– Chronic low-grade systemic inflammation (pro-inflammatory cytokine elevation)

Respiratory and ENT

– Asthma exacerbations (stress and emotional triggers)

– Hyperventilation syndrome and breathing pattern disorders

– Chronic sinusitis flares related to stress-related immune changes

Endocrine and hormonal

– HPA axis dysregulation (chronic cortisol elevation or blunted cortisol rhythms)

– Adrenal hormone imbalance manifestations (fatigue, energy dysregulation) — often described as HPA-axis dysfunction

– Thyroid disease symptom exacerbation (stress can worsen hypothyroid/hyperthyroid symptoms)

– Menstrual irregularities, dysmenorrhea, amenorrhea

– Reduced libido, sexual dysfunction, erectile dysfunction

– Fertility difficulties and stress-related menstrual cycle disruption

– Weight changes driven by stress-related hormonal and behavioral effects

Neurological and fatigue-related

– Chronic fatigue syndrome / myalgic encephalomyelitis (CFS/ME) (stress often precedes or worsens)

– Post-concussive–like cognitive fatigue from chronic stress

– Exacerbation of neurological disorders (e.g., seizures in some people)

Dermatologic and hair

– Eczema (atopic dermatitis) flares

– Psoriasis exacerbations

– Acne flares

– Alopecia areata (stress-related hair loss or worsening)

– Chronic pruritus (itch) and stress-triggered skin picking (excoriation)

Dermato-dental and oral

– Mouth ulcers (aphthous ulcers) and canker sores

– Gingivitis and periodontal disease exacerbation (via immune and behavioral pathways)

– Xerostomia (dry mouth) and dental decay from stress-related behaviors

Reproductive, pregnancy, and perinatal

– Sexual dysfunction (decreased desire, performance problems)

– Menstrual cycle disturbances and premenstrual syndrome worsening

– Increased risk of adverse pregnancy outcomes when stress is high (preterm birth, low birth weight) — multifactorial

Dermatome, sensory, and autonomic

– Dizziness, lightheadedness, syncope episodes linked to autonomic imbalance

– Paresthesias or numbness sensations associated with hyperventilation or tension

Other common stress-related physical consequences

– Reduced exercise capacity and slower physical recovery

– Poor wound healing and recovery after surgery

– Increased pain sensitivity (central sensitization)

– Sleep-disordered breathing worsened by stress-related insomnia and weight changes

– Medication overuse headaches (from analgesic overuse to manage stress-related headaches)

Conditions where stress is a known trigger or exacerbating factor (summary)

– Autoimmune disease flares (RA, lupus, psoriasis, MS)

– Gastrointestinal inflammatory conditions (IBD)

– Chronic pain syndromes (fibromyalgia, tension headache)

– Cardiometabolic disease progression (hypertension, CAD, diabetes)

– Psychiatric-to-physical cascade: mental disorders leading to physical illness via behaviors (substance use, poor diet, inactivity, poor sleep)
