We all have days when you’re so hungry that you end up eating more than what your body allows. While it may seem satisfying at the moment, practically inhaling your food like that can cause you issues later on, like causing you bloating. You may have noticed how you get bloated after you eat food like ramen noodles and other processed snacks like chips etc., but what is that? Basically, you get bloated because there is a lot of air in your stomach. Bloating is that feeling of fullness or swelling in your abdomen, is often caused by gas buildup in your gut. While everyone swallows some air while eating and drinking, excessive air intake can lead to bloating, burping, and discomfort. Certain foods and drinks can also contribute to gas. Bloating can sometimes make your belly appear larger (distention) and can be uncomfortable or even painful. Though usually more of a nuisance than a serious medical issue, bloating after eating is often preventable.

The Best Way To Avoid Bloating

The most effective way to combat post-meal bloating is to eat slowly and thoroughly chew your food. This helps prevent swallowing excess air, a common culprit behind bloating, especially for those who frequently burp. Thorough chewing also aids digestion by breaking food into smaller particles, making it easier for your gut to process.

This simple change can involve taking smaller bites, using smaller utensils, chewing your food more times before swallowing, or taking short breaks between bites to sip water or put down your utensils.

This practice offers additional benefits. Eating slowly can help you feel full with less food, which can be beneficial for weight management. It takes approximately 20 minutes for your brain to register fullness. Eating too quickly, on the other hand, is associated with weight gain.

Slowing down also helps you eat more mindfully. While it is understandable that sometimes you are eating because you have had a long day or no proper meal, when you are eating too quickly, not only are you not giving your body time to understand the amount of food it is consuming, causing you to overeat, but you are also not chewing properly, aiding to the inevitable bloating. Chewing properly allows you to focus on the aroma, flavors, and textures of your food. Mindful eating involves minimizing distractions and paying attention to your body's hunger and fullness cues without judgment. This practice can reduce stress and support healthy digestion by promoting relaxation.

More Ways to Prevent and Treat Bloating

Beyond slowing down, several other strategies can help prevent bloating. Eating smaller, more frequent meals prevents overloading your gut and reduces gas production. Remember to sit down and eat, avoiding eating on the go, which often leads to rapid eating and overconsumption. Regular exercise can also improve digestion and prevent bloating. Gentle activities like walking can be particularly helpful when you're feeling bloated. Massaging your stomach from right to left can also help release trapped gas.

Over-the-counter (OTC) medications like simethicone or charcoal capsules can provide relief. If you're also experiencing constipation, consult your doctor. While fiber is generally beneficial, insoluble fiber (found in the outer layers of plant foods like whole grains, nuts, and seeds) can sometimes exacerbate bloating and gas. Soluble fiber supplements, such as psyllium, are often better tolerated.

Several habits can contribute to bloating and should be avoided or limited. These include chewing gum, sucking on hard candy, drinking carbonated beverages, using a straw, and talking while eating or drinking. All of these can increase the amount of air you swallow. Certain carbohydrates can also trigger gas production in some individuals. When these carbohydrates reach the large intestine, bacteria break them down, leading to gas. Consuming too much fiber or high-fat foods can also contribute to bloating. If you suspect specific foods are triggering your bloating, consult your healthcare provider or a registered dietitian for personalized advice.

As pollution levels rise in October, doctors warn that exposure to particulate matter can affect lung and heart health, aggravate existing respiratory conditions, and cause symptoms even in otherwise healthy individuals, particularly as winter approaches.

PM2.5 and PM10 can irritate the respiratory tract, while fine particles such as PM2.5 can penetrate deep into the lungs, with some entering the bloodstream.

Delhi woke up to poor air quality on Thursday, with the Commission for Air Quality Management’s (CAQM) AQI dashboard recording an Air Quality Index (AQI) of 226 across Delhi-NCR at 7 am.

As per the CAQM’s dashboard, some areas of the national capital recorded very poor air quality, with an average AQI of 307.

The Commission for Air Quality Management (CAQM) on Wednesday imposed Stage I of the Graded Response Action Plan (GRAP) across Delhi-NCR after the capital's air quality slipped into the 'poor' category.

According to the Air Quality Early Warning System, Delhi's air quality is likely to remain in the 'poor' category until October 23. The forecast for the following six days also indicates that pollution levels are likely to remain in the same category.

How Air Pollution Affects Lung And Heart Health

Dr. Amit Kumar Mandal, Senior Director - Pulmonology, Paras Health Panchkula, told HealthandMe that air pollution can cause inflammation in the airways and worsen asthma, chronic obstructive pulmonary disease (COPD) and other respiratory conditions. It can also increase the risk of cardiovascular complications.

The effects may not always be immediately noticeable. People may experience persistent coughing, throat irritation, wheezing or breathlessness. Repeated exposure over time can contribute to more serious health problems, even in people without pre-existing conditions.

Dr. A.S. Sandhya, Consultant, Pulmonary & Sleep Medicine, Kailash Hospital & Neuro Institute, told HealthandMe that October can mark the beginning of a prolonged period of poor air quality in Delhi-NCR.

When pollution combines with changing weather conditions, people with asthma, bronchitis and COPD may experience more frequent symptoms. However, healthy individuals can also develop eye irritation, coughing, throat discomfort and reduced exercise tolerance after exposure to polluted air.

Doctors recommend monitoring daily AQI levels and limiting exposure when air quality is poor.

Dr. Mandal advises reducing prolonged outdoor activity and avoiding exercise near busy roads during high-pollution periods. Children, older adults, pregnant women and people with respiratory or heart conditions should take extra precautions.

Dr. Sandhya recommends limiting strenuous outdoor exercise when pollution levels are high and using a well-fitted N95 mask when outdoor exposure cannot be avoided.

Indoor air quality also matters, particularly for children and older adults who spend extended periods at home. Air purifiers with suitable filtration may help reduce indoor particulate matter, although they do not eliminate all pollutants.

When To Seek Medical Advice

People should not ignore persistent coughing, wheezing or unusual breathlessness. Those experiencing persistent breathing difficulties, chest discomfort or worsening respiratory symptoms should consult a doctor.

People with existing medical conditions should follow their treatment plans and seek medical advice if their symptoms worsen.

Taking preventive measures now, rather than waiting for pollution to peak in winter, can help reduce exposure and the risk of avoidable health complications in the months ahead.

Climate change is not just raising temperatures and intensifying extreme weather. It may also affect digestive health by disrupting food production, threatening water security and changing the spread of gastrointestinal infections, according to two leading gastroenterology experts from the World Gastroenterology Organization (WGO).

Climate change can contribute to heat-related illnesses and influence the geographic spread of infectious diseases, especially in countries like India.

A February 2025 review in The Lancet Planetary Health outlines how the combined effects of climate change could affect the human gut microbiome, including through food insecurity, malnutrition and exposure to disease-causing pathogens. These challenges could alter the composition of gut microbial communities worldwide.

Research suggests that heat stress may alter gut microbes, digestion and immune function. It may also increase intestinal permeability, potentially allowing toxins and pathogens to enter the bloodstream.

Climate-related drought can disrupt food production and reduce access to nutritious food, potentially affecting the gut microbiome. Environmental changes may also influence food- and waterborne pathogens, increasing infection risks where access to safe water and sanitation is limited.

Speaking to HealthandMe, Professor Geoffrey Metz, professor of medicine at the University of Melbourne, said climate change was becoming an increasing concern for gastrointestinal health.

“Certainly, with global warming, we're seeing a lot more infectious diseases in the gastrointestinal tract,” Metz said.

Climate change can affect digestive health through several interconnected pathways, including water availability, food production and infectious diseases.

Metz said the consequences of global warming extend beyond rising temperatures.

“The other thing, of course, with global warming—and this is a major interest of the World Gastroenterology Organisation—is that it's not just making us hot, but it's also creating more drought, which interacts with food production. So there's less food available, impacting our nutrition.”

Drought can disrupt food production and reduce food availability, raising concerns about nutrition. Changes in water availability can also make safe food preparation and hygiene more difficult.

However, the extent to which these environmental changes contribute to specific gastrointestinal diseases requires further investigation.

Safe Water And Food Hygiene Remain Essential

Professor Carolina Olano, professor of gastroenterology in Montevideo, Uruguay, and president of the WGO, highlighted the role of environmental factors in digestive diseases.

“Well, I think it's a combination of many factors. You know that there are some things related to genetics, and we have genetic predispositions to some diseases. But there are also environmental factors related to different diseases, and climate change has an impact too. We are working very hard at the World Gastroenterology Organisation to understand how climate change is affecting different diseases.”

Olano also emphasised the importance of safe drinking water and food hygiene in preventing infections.

“It's also important to have a varied diet and to drink safe, clean water, making sure that the water we drink is safe. Food hygiene is also extremely important.”

She told HealthandMe that handwashing was another simple preventive measure.

“We learned from the COVID pandemic that handwashing before eating is extremely important. These are things we can do every day without spending anything, and they can help prevent many important diseases, especially those related to infections.”

The effects of climate change may extend beyond the digestive system, affecting multiple aspects of health.

“Global warming is not just affecting how we feel; it's also having an effect on heart disease, lung disease, gastrointestinal disease, obstetrics and gynaecology,” said Metz, who is also the former president of the WGO.

Olano also pointed to population movements as a factor to consider when assessing environmental and health risks.

“As you know, it's not only about weather and climate change. It's also about how populations move from one country to another and what the impact of these movements is when people move from one region to another.”

“Because, as you know, it's not only about weather and climate change. It's also how populations move from one country to another and what the impact of these movements is when people move from one region to another.”

Understanding these connections is important as researchers investigate how climate-related environmental changes may influence disease patterns across regions.

What Can People Do To Protect Their Digestive Health?

While individuals cannot control climate-related changes, Olano highlighted everyday measures that can help prevent infections and support digestive health:

• Drink safe, clean water.
• Maintain food hygiene and handle food safely.
• Wash hands before eating.
• Follow a varied diet.
• Stay physically active.

She also stressed the importance of seeking medical advice about hepatitis prevention, vaccination and testing where appropriate, as well as colorectal cancer screening.

Climate change presents a broader public health challenge, but safe water, food hygiene and infection prevention remain important measures for reducing avoidable digestive health risks.

Depression affects millions of people worldwide, but not everyone responds equally well to treatment. Now, researchers at the University of Sydney have identified a new subtype called “circadian depression,” which is linked to the body’s internal clock and may help explain why conventional antidepressants work less well for some people.

The subtype was identified in nearly a quarter of participants with severe, recurrent or persistent depression in an Australian study. Researchers say recognizing its characteristics could help clinicians identify patients who may benefit from different treatment approaches.

“Our research has identified circadian depression as a new subtype, affecting around a quarter of people in our study into those with severe, recurrent or persistent depression,” said Dr. Emiliana Tonini from the Brain and Mind Centre at the University of Sydney.

“Depression is not a uniform illness and understanding the characteristics of different subtypes mean that we can give people earlier access to treatments that will be most effective for them,” she added.

Circadian Depression: What Are The Key Symptoms?

Circadian depression is linked to the body’s 24-hour internal clock, which regulates the sleep-wake cycle. Researchers identified several symptoms and characteristics associated with this subtype, including:

• A seasonal pattern of illness

• Sleeping longer during depressive episodes

• Waking up feeling very tired

• Being a night owl

To investigate the subtype, researchers analyzed clinical and genetic data from more than 10,000 people with depression who participated in the nationwide Australian Genetics of Depression Study.

Of these, 2,604 participants, or nearly 25%, were identified as having circadian depression.

The researchers also found that people with this subtype were more likely to experience depression earlier in life and had more severe symptoms, including mania and higher levels of suicidal thoughts.

In addition, these participants had a higher genetic risk for inflammatory and cardiovascular health problems, as well as major neurodevelopmental disorders, including attention-deficit/hyperactivity disorder (ADHD).

The findings, published in the British Journal of Psychiatry, offer insights into the genetic mechanisms associated with circadian depression and may help explain why conventional treatments, such as selective serotonin reuptake inhibitors (SSRIs), work less well for some people with this subtype.

How Does Circadian Depression Differ In Treatment Response?

Antidepressants such as SSRIs and serotonin-norepinephrine reuptake inhibitors (SNRIs) are commonly used to treat depression. However, the researchers reported that these medications were less effective and associated with more side effects in people with the circadian subtype.

Because circadian depression is linked to the body’s internal clock, treatments targeting circadian rhythms may be relevant for some patients. These include light therapy, melatonin and melatonin-targeted antidepressants.

“Because circadian depression is linked to people’s internal body clock, treatments targeting the circadian rhythm, such as light therapy and melatonin, may be much more relevant, and clinicians should reach for these much earlier in people with this presentation,” said Dr. Jacob Crouse, co-senior author of the study, from the Brain and Mind Centre.

“For those who find that antidepressants are not working for them, it is important to speak to your clinician for advice about your individual circumstances,” he added.

Professor Ian Hickie, co-director of the Brain and Mind Centre and a clinical psychiatrist, emphasized that failing to recognize circadian depression in young people could contribute to early treatment failures and more side effects.

“We really want young people to receive the most appropriate treatment early in their course of illness.

“Most young people will be offered SSRIs first up, but for at least a quarter there are better circadian-focused medical and behavioural options to help treat and manage their condition.”

The findings suggest that identifying circadian depression could help clinicians consider more tailored treatment approaches. However, the study does not establish that body-clock disruption causes depression or that every person identified with this subtype will respond better to circadian-focused treatments. Patients should consult their clinicians before making any changes to prescribed medication, the experts said.
