In recent years, doctors across India are seeing a growing number of patients who arrive with a cluster of vague but distressing symptoms. Weeks of ongoing fatigue, recurring headaches, stomach upset, restless sleep, and a persistent feeling of ‘brain fog.’ Each symptom alone may seem minor, but together they make patients feel unwell and uneasy. Often, standard blood tests, scans, and physical exams do not reveal any abnormalities. This situation reflects a rising concern in medicine: overlapping syndromes.
We spoke to Dr Balakrishna GK, HOD and Senior Consultant Internal Medicine, Gleneagles BGS Hospital Kengeri, Bengaluru, who shared insights on the same.
What are Overlapping Syndromes?
Unlike a single disease with clear signs, overlapping syndromes describe situations where different body systems—gut, brain, immune, and hormonal—are involved at the same time. Symptoms overlap, blur, and reinforce each other.
“Some patients come in describing stomach upsets that resemble irritable bowels, alongside recurring headaches. Others may struggle with constant fatigue, body aches, and mood changes. Each symptom on its own may not clearly explain what is happening, but taken together, they often reflect a deeper problem in how the body is handling stress, inflammation, and energy balance,” said Dr Balakrishna.
Why Is This Rising In India?
Several lifestyle and environmental changes explain this rise. Modern urban living encourages long hours of sitting, erratic meal timings, and high intake of processed foods. Air pollution, noise, and workplace stress add invisible burdens to the body. Sleep patterns are also disrupted by late-night screen use.
Over time, these factors keep the immune system slightly activated, hormones imbalanced, and digestion unsettled. The result is not always a ‘disease’ in the conventional sense, but a network of interacting symptoms that reduce quality of life.
Awareness has changed as well. Many people no longer dismiss fatigue or brain fog as unimportant and are more willing to talk about them. Doctors, in turn, are learning to connect these scattered complaints, even when they don’t fit neatly into medical textbooks.

Common Complaints That Overlap
Patients with overlapping syndromes often share certain recurring issues:
- Unrelenting fatigue even after rest.
- Headaches or migraines are tied to stress, hormonal shifts, or digestive triggers.
- Digestive problems, such as bloating, acidity, or irregular bowel habits.
- Cognitive concerns like forgetfulness, poor focus, or mental exhaustion.
- Mood changes, including irritability, anxiety, or low motivation.
Because these symptoms are widespread and variable, they are sometimes dismissed as “all in the head.” In reality, they reflect how different systems in the body influence one another.
Why Is Diagnosis Difficult
Standard medical investigations are designed to detect clear-cut disease—an infection, a fracture, a metabolic disorder. However, overlapping syndromes operate at a subtler level. “Inflammation may be low-grade, hormone changes may be within 'normal' limits, and gut disturbances may not show up on routine tests. This does not mean the patient’s experience is imagined. Rather, it highlights the limitations of a purely disease-centered model. For many patients, the path to relief begins not with a single test but with a careful conversation about lifestyle, stress, and triggers,” explained Dr Balakrishna.
How Can These Conditions Be Managed?
There is no one-size-fits-all approach. Management is individualised and usually combines medical care with lifestyle strategies:
- Diet: Emphasising balanced, home-cooked meals with fruits, vegetables, whole grains, and healthy fats, while cutting down on processed items and excessive caffeine.
- Physical activity: Regular movement, whether walking, yoga, or light exercise, supports circulation, mood, and digestion.
- Stress management: Focusing on mindful moments, taking deliberate breaths, and engaging in hobbies can help the body manage stress.
- Sleep hygiene: Consistent sleep and limiting late-night screens give the nervous system time to repair and reset.
- Medical input: In some cases, targeted therapies, whether for migraines, gut health, or hormonal balance, are added to support recovery.
The focus is not only on symptom relief but also on restoring resilience, so patients can function well in daily life.
Changing the Conversation
For many in India, acknowledging these problems can be hard. When symptoms have no clear name, stigma often keeps people quiet. Doctors should reassure patients that their experiences are genuine. Overlapping syndromes are not imagined; they signal that several systems need care. With timely recognition, proper guidance, and lifestyle changes, patients can recover strength and focus.
Bottomline
Dr Balakrishna concluded, “India is facing a quiet shift in the way illness presents. Not all health problems arrive with a single diagnosis or a clear test result. Sometimes, the body speaks in fragments—fatigue here, a headache there, a foggy mind, or a restless gut. Notice these signals, pay attention to the whole picture, and seek help promptly. If you or someone you know experiences multiple unexplained symptoms, take them seriously. A qualified physician can review the patterns, identify underlying issues, and suggest steps to restore well-being.”
