Study Links High Sugar Intake to Worsening Asthma Symptoms

ISLAMABAD: A new scientific study has suggested that excessive sugar consumption may worsen asthma symptoms by increasing inflammation in the lungs, adding to the growing list of health risks associated with a high-sugar diet.

The study, published in the journal Nutrients, found that consuming large amounts of sugar can temporarily aggravate lung inflammation, potentially increasing the risk of asthma flare-ups and allergic reactions.

Researchers conducted experiments on mice that were given access to sweetened milk in addition to their regular diet. According to the study, negative effects became evident within two weeks, with increased inflammation observed in the animals’ lungs.

The researchers said the findings are the first to demonstrate how quickly high sugar intake can intensify inflammation associated with asthma.

Asthma is a chronic respiratory disease that currently has no cure, although its symptoms can be managed through medication and lifestyle adjustments. The condition affects the lungs and airways, making breathing difficult and interfering with daily activities.

During an asthma attack, the airways become inflamed and the surrounding muscles tighten, leading to symptoms such as coughing, wheezing, chest tightness, and shortness of breath.

The researchers noted that while excessive sugar intake is commonly associated with tooth decay, obesity, and an increased risk of type 2 diabetes and high blood pressure, its potential impact on asthma has received far less attention.

They concluded that the findings strengthen recommendations to limit sugar consumption, particularly for people living with asthma, as high sugar intake may disrupt the immune system and trigger inflammatory responses that can worsen the condition.

The researchers emphasized that the findings are based on an animal study, and further research involving humans is needed to confirm the effects.
