More Than Just Tired: Dr. Nishanth Reddy on Unmasking Hidden Causes of Fatigue in Young Adults

Have you ever wondered why you feel exhausted even after a full night’s sleep? For many young adults, fatigue is dismissed as the result of late nights, poor diet, or busy schedules. But often, the real cause lies much deeper. Hidden medical issues, mental health challenges, and lifestyle factors can silently drain your energy and impact your quality of life. Fatigue isn’t just “being tired”; it’s your body’s way of signalling that something needs attention. Dr. Nishanth Reddy, Consultant, Internal Medicine in Star Hospital, Hyderabad, explains how to recognise the hidden causes of fatigue, when to seek help, and what steps can restore your energy in this article.

Understanding the Hidden Causes of Fatigue

While lack of sleep and unhealthy eating are common culprits, several overlooked factors can trigger persistent tiredness:

Medical Conditions:

● Anaemia: Low red blood cell count reduces oxygen delivery, causing constant fatigue.

● Hypothyroidism: An underactive thyroid slows metabolism, leading to low energy.

● Sleep Apnea: A condition where interrupted breathing during sleep reduces oxygen supply to the body, leading to fatigue, body aches, and daytime exhaustion.

● Interrupted breathing during sleep results in poor rest and daytime exhaustion.

● Other conditions like fibromyalgia, lupus, inflammatory bowel disease, and even certain cancers can manifest with fatigue as an early symptom.

Mental Health Factors:

● Stress, anxiety, and depression can sap motivation, disrupt sleep, and drain emotional reserves.

● Chronic burnout from overwork can lead to both mental and physical exhaustion.

Lifestyle Triggers:

● Poor sleep hygiene, irregular schedules, and late-night screen time.

● Nutrient deficiencies in vitamins like B12, D, and minerals like iron.

● Dehydration, excessive caffeine, or alcohol intake.

● Sedentary lifestyle and lack of exercise.

● Disrupted body clock from shift work or excessive technology use.

The Alarming Statistics

Recent surveys highlight how widespread fatigue has become among young adults in India:

● 85% wake up feeling fatigued (Bayer Supradyn Fatigue Survey).

● 83% frequently need breaks due to tiredness.

● 74% struggle with daytime sleepiness and reduced productivity.

● 69% find it hard to start or complete tasks, and 66% can’t finish daily activities.

● Nutritional deficiencies are common, especially in urban areas like Pune and Bengaluru.

● Chronic Fatigue Syndrome (CFS) may affect over 12% of women aged 18–50, according to The Hindu.

When to Seek Medical Advice

If fatigue persists despite improving sleep, diet, and activity levels or if it comes with symptoms like fever, weight changes, or pain, it’s time to consult a doctor. Early detection of underlying medical or psychological conditions can prevent long-term health issues.
