Mysterious poisoning: Cattle toll touches 71

Bengaluru: As air quality continues to worsen across several parts of the city, hospitals in Bengaluru are reporting a steady rise in patients suffering from respiratory illnesses such as asthma, bronchitis and Chronic Obstructive Pulmonary Disease (COPD), health officials and doctors said.

Data from the Suvarna Arogya Suraksha Trust (SAST) shows that 3,891 patients received treatment for respiratory ailments between April and November 2024. The figure rose to 4,187 during the same period in 2025.

Private hospitals, too, are witnessing a 10–15 per cent year-on-year increase in such cases.

While doctors caution that the rise cannot be attributed solely to air pollution, a significant number of patients are non-smokers with no prior history of respiratory disease.

“Nearly 70 per cent of the patients we see are non-smokers with no previous respiratory issues. When other causes are ruled out, air pollution emerges as the most likely factor,” said Dr Manjunath PH, consultant interventional pulmonologist at a hospital in Kengeri.

Doctors noted that patient footfall spikes during the winter months and around Deepavali, when air quality typically worsens.

“There is a clear correlation between poor air quality and the rise in cases. People commonly present with persistent cough, breathlessness and irritation of the respiratory tract, indicating the impact of polluted air on their health,” said Dr Sheetal Chaurasia, consultant in pulmonary medicine at a private hospital in Whitefield.

Dr Chaurasia added that respiratory tract infections are also on the rise.

“Poor air quality leads to chronic airway inflammation, making the airways more vulnerable to infections. We are seeing an increase in both upper and lower respiratory tract infections,” she said.

Patients with pre-existing respiratory conditions remain the worst affected.

“For those already diagnosed with respiratory illnesses, deteriorating air quality significantly worsens the condition. Both the frequency and severity of attacks increase sharply,” said Dr Vandana P, a pulmonologist at a hospital on Bannerghatta Road.

Doctors also flagged a worrying trend of rising respiratory problems among younger adults and children.

To reduce exposure, they advised people to wear masks while travelling on two-wheelers or autos and ensure adequate ventilation at home to minimise indoor air pollution.

Dakshina Kannada MP Capt Brijesh Chowta has urged the Centre to give high priority to offshore wind energy generation along the Mangaluru coast, citing its strategic importance to India’s green energy and port-led development goals.

Raising the issue in the Lok Sabha under Rule 377, Chowta said studies by the National Institute of Oceanography have identified the Mangaluru coastline as part of India’s promising offshore wind ‘Zone-2’, covering nearly 6,490 sq km. He noted that the region’s relatively low exposure to cyclones and earthquakes makes it suitable for long-term offshore wind projects and called for its development as a dedicated offshore wind energy zone.

Highlighting the role of New Mangalore Port, Chowta said its modern infrastructure, multiple berths and heavy cargo-handling capacity position it well as a logistics hub for transporting and assembling large wind energy equipment.

He also pointed to the presence of major industrial units such as MRPL, OMPL, UPCL and the Mangaluru SEZ, which could serve as direct buyers of green power through power purchase agreements, improving project viability and speeding up execution.

With Karnataka’s peak power demand crossing 18,000 MW in early 2025, Chowta stressed the need to diversify renewable energy sources. He added that offshore wind projects in the Arabian Sea are strategically safer compared to the cyclone-prone Bay of Bengal.

Calling the project vital to India’s target of 500 GW of renewable energy by 2030, Chowta urged the Ministry of New and Renewable Energy to initiate resource assessments, pilot projects and stakeholder consultations at the earliest.
