Dizziness, Fatigue and Palpitations: Causes, Conditions & When to See a Doctor

Early recognition of Anxiety Disorder is critical — treatment initiated at the earliest stage is significantly more effective and prevents long-term complications. Understanding the subtle initial presentations allows patients and clinicians to act before the condition progresses.

Possible Causes of Dizziness, Fatigue and Palpitations

Conditions that commonly produce all three symptoms together

  1. 1Early Anxiety Disorder often produces non-specific symptoms: fatigue, malaise, or mild discomfort
  2. 2Early warning signs may include: anxiety, palpitations, insomnia, dizziness
  3. 3Subclinical changes in blood tests, blood pressure, or weight often precede overt symptoms
  4. 4Family history and risk factors increase the probability that vague symptoms represent early Anxiety Disorder
  5. 5Screening programmes are designed specifically to detect Anxiety Disorder before symptoms appear
  6. 6Core management targets: reducing anxiety, palpitations, insomnia and preventing disease progression

Emergency Red Flags

Seek immediate medical attention if you experience any of these

Any of the characteristic symptoms of Anxiety Disorder — even mild — in a high-risk individual
Progressive worsening of early warning signs over weeks
Laboratory abnormalities (e.g., blood sugar, inflammatory markers) without full symptoms
Unexplained weight loss, night sweats, or fatigue persisting >2 weeks
Strong family history of Anxiety Disorder combined with new relevant symptoms

When to See a Doctor

Schedule a consultation if you notice these signs

You have risk factors for Anxiety Disorder and develop any of the characteristic early symptoms
Screening tests return borderline or abnormal results
You have a strong family history and have not yet been screened for Anxiety Disorder
Scheduled monitoring appointments — do not skip even when feeling well

Conditions That Cause Dizziness, Fatigue and Palpitations

8 conditions are associated with this three-symptom pattern

Anxiety Disorder
Anxiety disorders are among the most common mental health conditions, characterized by excessive fear, worry, or nervousness that interferes with daily activities. Types include generalized anxiety disorder (GAD), panic disorder, and social anxiety.
Cardiac Arrhythmia
Cardiac arrhythmia refers to irregular heart rhythms — the heart beats too fast, too slow, or with an irregular pattern. Some arrhythmias are harmless, while others (like atrial fibrillation) significantly increase the risk of stroke and heart failure.
Aortic Stenosis
Aortic stenosis is narrowing of the aortic valve opening, restricting blood flow from the heart. It causes exertional chest pain, syncope, and heart failure; valve replacement is required for severe symptomatic disease.
Iron Deficiency Anemia
Iron deficiency anemia is the most common nutritional deficiency worldwide, caused by inadequate dietary intake, blood loss, or malabsorption. It causes fatigue, pallor, shortness of breath, and pica; iron supplementation is the treatment.
Atrial Fibrillation
Atrial fibrillation (AFib) is the most common cardiac arrhythmia, characterized by rapid and irregular atrial beating. It significantly increases stroke and heart failure risk.
Hypoglycemia
Hypoglycemia is low blood sugar, typically below 70 mg/dL. Most common in people with diabetes, it causes rapid neurological and adrenaline-driven symptoms requiring prompt treatment.
Anemia
Anemia is a condition where there are insufficient healthy red blood cells to carry adequate oxygen to body tissues. It has many causes including nutritional deficiencies, chronic disease, and blood loss.
Pulmonary Arterial Hypertension
Pulmonary arterial hypertension is high blood pressure in the arteries supplying the lungs. It causes the right side of the heart to work harder, eventually leading to heart failure.
