Heartburn in Older Adults — Geriatric Causes & Management

Heartburn in older adults is influenced by age-related physiological changes: reduced organ reserve, altered drug metabolism, comorbidities and polypharmacy. Atypical presentations are common — older patients may not display the classic signs seen in younger people, making diagnosis more challenging and thorough assessment more important.

Why Heartburn Occurs In Older Adults

→Reduced thirst sensation increases chronic dehydration risk in those over 65
→Multiple medications increase adverse effect and drug-interaction likelihood
→Age-related decline in immune function alters infection presentation
→Postural hypotension is more prevalent, worsening many symptoms on standing
→Cognitive changes may mask or alter symptom reporting — carer input is valuable

Common Causes of Heartburn

1
Infections and inflammation — bacterial, viral, or autoimmune triggers activate heartburn
2
Metabolic disturbances — hormonal imbalances, nutrient deficiencies, or blood sugar changes
3
Structural or vascular causes — tissue damage, nerve compression, or circulatory problems
4
Psychological factors — stress, anxiety, and depression can produce measurable physical heartburn
5
Underlying conditions such as Gastritis, Peptic Ulcer, Gerd frequently present with heartburn as a core feature
6
Dangerous heartburn is often linked to acute conditions such as Gastritis, Peptic Ulcer
7
Vascular emergencies — stroke, pulmonary embolism, heart attack — can present with heartburn
8
Severe infections (sepsis, meningitis) may cause heartburn as a systemic alarm signal
9
Toxic exposures or medication overdose can trigger acute heartburn
10
Trauma or internal injury causing tissue or organ damage
11
Tension and muscle tightness — often relieved by stretching, heat, and relaxation
12
Dehydration — respond to increased fluid intake within 30–60 minutes
13
Stress and anxiety — improved by breathing exercises, mindfulness, and rest
14
Inflammatory processes — NSAIDs or antihistamines can provide relief
15
Positional or ergonomic factors — correcting posture or position resolves heartburn
16
Infectious causes: viral, bacterial, or fungal pathogens triggering systemic or localised heartburn
17
Inflammatory/autoimmune: the body's immune response producing heartburn as a bystander effect
18
Metabolic: disorders of thyroid, adrenal, or blood glucose regulation
19
Structural/mechanical: nerve compression, joint damage, or organ enlargement
20
Underlying conditions: Gastritis, Peptic Ulcer, Gerd, Esophageal Cancer are among the leading identifiable causes
21
Cortisol and adrenaline surges alter inflammation, pain sensitivity, and muscle tension
22
Autonomic dysregulation affects heart rate, digestion, breathing, and vascular tone
23
Psychological hypervigilance amplifies the perception of heartburn
24
Chronic stress disrupts sleep, which independently worsens heartburn
25
Behavioural changes under stress (poor diet, caffeine, inactivity) contribute to heartburn
26
Cortisol nadir at night: cortisol (the body's natural anti-inflammatory) is lowest at 3–4 AM, allowing inflammation to peak — worsening heartburn in early morning
27
Dehydration during sleep: 6–8 hours without fluid intake concentrates blood and reduces tissue hydration, intensifying heartburn
28
Sleep position: sustained pressure, poor neck or spinal alignment, or restricted circulation overnight amplifies heartburn by morning
29
Inflammatory diseases (rheumatoid arthritis, ankylosing spondylitis): classic morning stiffness and heartburn lasting >30 minutes indicates active inflammation
30
Nocturnal hypoglycaemia or respiratory changes: low blood sugar or mild oxygen desaturation during sleep contributes to morning heartburn
31
Exercise-induced blood flow redistribution: during exertion, blood is diverted to working muscles, which can trigger heartburn in other tissues
32
Dehydration and electrolyte loss: sweat-driven fluid loss increases heartburn particularly in hot environments
33
Lactic acid accumulation and metabolic acidosis: intense exercise generates lactic acid, causing muscle heartburn and systemic effects
34
Post-exercise inflammatory response: micro-tears in muscles trigger a local inflammatory cascade that produces heartburn 12–48 hours later (DOMS)
35
Underlying conditions such as Gastritis, Peptic Ulcer may be unmasked by the physiological stress of exercise
36
Sympathetic nervous system activation: adrenaline and noradrenaline increase heart rate, muscle tension, and pain sensitivity — all of which worsen heartburn
37
HPA axis activation: cortisol spikes acutely under stress, then becomes dysregulated with chronic stress, driving systemic inflammation
38
Muscle tension: stress causes involuntary clenching and guarding, amplifying musculoskeletal heartburn
39
Hyperventilation: stress-induced breathing changes alter blood CO₂ and pH, contributing to heartburn including dizziness, tingling, and chest tightness
40
Gut-brain axis dysregulation: stress disrupts gastrointestinal motility and microbiome balance, causing or worsening visceral heartburn
41
Acute (minutes to hours): benign causes such as tension, dehydration, hypoglycaemia, or transient vascular changes
42
Subacute (days to 1–2 weeks): infections, post-viral syndromes, minor injuries, or medication effects
43
Prolonged (2–6 weeks): inflammatory responses, subacute infections, or early manifestations of conditions like Gastritis, Peptic Ulcer
44
Chronic (>6 weeks or recurring): underlying chronic disease, functional disorders, or inadequately treated acute causes
45
Episodic (recurs and remits): migraine, IBS, asthma, anxiety disorders — each episode may be brief but the condition is chronic
46
GP (General Practitioner): first point of contact for all new heartburn — can diagnose common causes and coordinate specialist referral
47
Relevant conditions like Gastritis, Peptic Ulcer, Gerd may require specific specialists for full evaluation
48
If heartburn has a clear systemic pattern, a general internist or hospital physician provides comprehensive assessment
49
For chronic or recurrent heartburn that has resisted primary care treatment, specialist input significantly improves outcomes
50
Emergency department: for sudden, severe, or neurologically associated heartburn that cannot wait for an appointment
