India’s major metro cities are grappling with a severe shortage of essential medical support and services, especially in urban areas where a significant portion of the population lives in slums or slum-like conditions. This situation highlights the urgent need for awareness about primary health issues in metros and finding effective solutions to address them, requiring the central government’s immediate attention.
A large percentage of metro residents belong to underprivileged or extremely poor backgrounds. They lack access to clean, safe living environments, proper sanitation, drinkable water, and other basic necessities essential for survival. In many cases, their living conditions are worse than those of rural populations, who at least enjoy cleaner air, better water quality, and healthier surroundings.
Given India’s rapid population growth, this crisis is expected to intensify in the coming decades. As more people move to urban areas, the pressure on already strained resources—such as housing, healthcare, and sanitation—will only worsen, leading to declining health standards and a rise in preventable diseases.
Immediate steps are needed to expand primary healthcare services for the urban poor, who are the most vulnerable to communicable diseases, respiratory infections, pollution, accidents, and injuries. However, the middle and upper classes are not exempt from metro-related health issues either. Many among them are increasingly suffering from life-threatening non-communicable diseases due to unhealthy lifestyles, environmental pollution, and the daily stress associated with traffic and urban living.
### Major Health Issues in Metro Cities
#### Communicable Diseases
Urban residents, particularly the poor, are frequently afflicted by communicable diseases such as malaria, dengue, chikungunya, and the flu. Poor sanitation and stagnant water in slum areas provide perfect breeding grounds for mosquitoes and viruses, contributing to recurring outbreaks. Alarmingly, deaths from these diseases are on the rise because current interventions are proving insufficient, with environmental factors like dust and pollution further exacerbating the problem.
A recent World Health Organization (WHO) study suggests that human behavior often contributes to the spread of these diseases. For example, infected individuals can transmit viruses to others, directly or indirectly, through environments like overcrowded trains, where sneezing and coughing make disease transmission nearly unavoidable.
#### Respiratory Diseases in Children
Respiratory diseases are another pressing issue, particularly for children in metro cities who are disproportionately affected due to their underdeveloped immune systems. Exposure to pollution caused by heavy traffic, industrial activities, and dust has severely impacted lung health. According to reports, nearly four in ten children in Delhi NCR have significant lung issues, and similar trends are found in other cities like Mumbai, Bangalore, and Kolkata. Poor air quality not only causes childhood respiratory illnesses but increases the risk of chronic conditions like asthma and heart diseases later in life.
#### Digestive Disorders
Digestive health is yet another growing concern in both urban slums and affluent metro societies. Poor dietary habits, reliance on processed foods, and sedentary lifestyles contribute to issues like indigestion, constipation, and gastric problems. In slum areas, lack of clean drinking water and proper sanitation often leads to conditions like diarrhea, which can sometimes be fatal. Meanwhile, wealthier urbanites face digestion-related issues stemming from stress, overconsumption of alcohol, and smoking.
#### Non-Communicable Diseases
Non-communicable diseases (NCDs)—such as cardiovascular diseases, cancer, diabetes, and obesity—are among the leading causes of deaths in metro cities, accounting for an alarming 61% of India’s mortality rate, according to WHO.
– **Cardiovascular Diseases**: Poor lifestyle choices, such as unhealthy diets, tobacco use, and lack of exercise, are the primary reasons for high rates of heart diseases among metro populations. Sedentary habits, reliance on convenience technologies like elevators and vehicles, and high stress levels also contribute to problems like high cholesterol and hypertension, leading to strokes and heart attacks.
– **Cancer**: Urbanization has also driven up cancer rates, with various types—such as breast, lung, and colon cancer—becoming increasingly common. Contributing factors include environmental pollution, unhealthy diets, and high-stress urban lifestyles. Experts predict a fivefold increase in cancer cases by 2025 if current trends persist.
– **Diabetes**: Rising obesity rates, poor eating habits, and inactivity have caused a surge in type 2 diabetes cases, making it one of the most prevalent lifestyle disorders in metro cities. This condition, if uncontrolled, can lead to serious complications and sudden health emergencies.
#### Accidents and Injuries
Road accidents are another critical issue. Poor traffic management, rash driving, and disregard for traffic rules contribute to a staggering number of deaths and injuries. Statistics reveal that India sees about 17 road-related deaths and 55 injuries every hour—an alarming figure that underscores the urgent need for better safety measures.

### Coping Solutions for Metro Health Issues
**Preventing Cardiovascular Diseases**
Adopting a healthy lifestyle is key to lowering the risk of heart-related issues. Regular exercise, adequate sleep, a balanced diet, stress management, and avoiding smoking and excessive alcohol intake can go a long way. Regular health check-ups for blood pressure, cholesterol, and blood sugar levels are also essential.
**Managing Respiratory Issues**
Quitting smoking is one of the most impactful steps to curb respiratory diseases. People should also use masks to minimize exposure to pollutants, especially in high-traffic or industrial areas. Government bodies must also ensure cleaner environments by implementing stricter rules for vehicular emissions and improving sanitation in urban slum areas.
**Improving Digestive Health**
Maintaining a healthy diet, rich in natural and unprocessed foods, is crucial for gut health. Quitting alcohol and tobacco while staying hydrated and engaging in physical activity can help prevent digestive disorders. Clean drinking water should also be ensured in slum areas, as diseases like diarrhea are largely preventable with proper sanitation.
**Combating Communicable Diseases**
Addressing preventable diseases like dengue and malaria requires better sanitation practices and regular pesticide use in areas with stagnant water. Community awareness programs can educate residents about early diagnosis and preventive measures, helping to minimize outbreaks of these debilitating illnesses.
**Reducing Road Accidents**
Stricter enforcement of traffic laws and better pedestrian infrastructure can reduce the risk of road accidents. Simple measures like using proper crossings, avoiding phone usage while walking, and offering first aid at accident sites could save countless lives.

Creating awareness about the primary health concerns in metro cities, alongside urgent intervention, is critical for improving urban life. Without immediate action, health outcomes for large swaths of the urban population will continue to deteriorate, leading to increased mortality and an unsustainable healthcare burden.
