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 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.
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.

Sleep disturbances are among the most debilitating symptoms of Alzheimer’s disease. It often appears years before significant memory decline and other symptoms.
A new study from researchers at the University of Kentucky suggests that this sleep loss may not be permanent.
Instead, it could be driven by an immune response in the brain that may be reversible, sparking hope for new treatments.
Published in the journal Alzheimer’s & Dementia, the study found that brain immune cells called microglia, rather than amyloid plaques themselves, are the primary cause of sleep disruption in Alzheimer’s disease.
In mouse-based trials, researchers were able to restore more than two hours of sleep per day by temporarily removing these immune cells, without reducing amyloid plaques.
For years, scientists believed that sleep problems in Alzheimer’s were caused by the accumulation of amyloid plaques or the gradual death of brain cells. However, this study points in a different direction.
Researchers discovered that when amyloid plaques begin forming in the brain, they activate microglia, the brain’s resident immune cells.
Instead of protecting the brain, these cells cause inflammation that keeps brain circuits active, preventing sleep.
Using a drug called pexidartinib (PLX3397), the researchers temporarily depleted around 87% of microglia in Alzheimer’s mouse models.
This restored over two hours of daily sleep, particularly non-rapid eye movement (NREM) sleep, which is essential for tissue repair, memory strengthening, and clearing waste products from the brain.
Notably, the improvement occurred without changing amyloid plaque levels, suggesting that inflammation is manageable.
Lead researcher Dr. Shannon L. Macauley, associate professor of physiology at the University of Kentucky College of Medicine, said, “Basically, we showed that it is not the plaques themselves, or solely dysfunctional neurons, that cause sleep loss but actually microglia.
Microglia are immune cells that, when they respond to plaques, kick off this elaborate cascade of inflammation, as if the microglia are partying all night, and keeping the brain awake.”
She also highlighted why losing restorative sleep can accelerate disease progression.
“That restorative sleep is super important for physical repair, learning and memory and washing out the toxins of the day. When Alzheimer’s patients lose this stage, they lose their brain’s primary cleaning cycle, creating a feed-forward loop that may drive further damage,” she explained.
First author Dr. Nicholas J. Constantino said one of the biggest surprises was that sleep problems did not worsen as amyloid plaques increased.
“I expected that as plaque burden became more severe, sleep disruption would also worsen. The disruptions in sleep… did not worsen by 18 months, despite more than double the amount of plaque burden,” Constantino said.

Poor sleep and Alzheimer’s create a vicious cycle. Sleep deprivation reduces the brain’s ability to clear amyloid-beta and tau proteins, which can accelerate disease progression, while worsening sleep.
Sleep disturbances affect up to half of people living with Alzheimer’s disease. The disease disrupts sleep due to various reasons:
Overactive microglia: As shown in the new study, immune cells become chronically activated by amyloid plaques, releasing inflammatory signals that keep the brain in a heightened state of activity.
Damage to sleep-regulating brain regions: Alzheimer’s progressively affects areas like the hypothalamus and brainstem that regulate the sleep-wake cycle.
Loss of NREM sleep: Due to lack of deep sleep, the brain’s ability to clear metabolic waste, including amyloid plagues weakens.
Circadian rhythm disruption: Degeneration of the brain’s internal clock leads to broken sleep and daytime drowsiness. This fuels confusion and agitation associated with the disease.

Obesity has always been considered as one of the contributors to heart disease, diabetes, and stroke.
Now, growing research suggests that excess body fat, particularly in your 40s and 50s, may also accelerate brain aging and raise the risk of long-term cognitive decline.
Researchers say that obesity is not just linked with memory problems but also to significant changes in the brain structure.
Maintaining a healthy weight, especially during midlife, could help prevent memory problems and overall cognitive decline.
A recent study by researchers at the University of Georgia followed more than 8,200 adults aged 50 years and older for nearly 24 years.
The researchers found that individuals whose body mass index (BMI) increased over time experienced faster declines in cognitive performance than it would with normal aging. Excess body weight affected several aspects of cognition, including memory, planning, decision-making, problem-solving, emotional regulation, and concentration.
Lead author Dr. Claire Sexton (University of Georgia College of Public Health) said, "Maintaining a healthy body weight throughout adulthood may be an important strategy for preserving cognitive health later in life."
The study adds to the evidence that preventing weight gain throughout adulthood could become crucial for reducing dementia risk.

Obesity causes chronic low-grade inflammation, which can potentially damaging neurons essential for learning and memory.
The brain relies on glucose for energy. Insulin resistance, common in obesity, may impair how brain cells use glucose, affecting memory and thinking.
Obesity increases the risk of hypertension, atherosclerosis and vascular disease, reducing blood supply to brain tissue and potentially accelerating cognitive decline.
Experts believe visceral fat, the fat surrounding internal organs, may be more damaging than body weight alone. It produces inflammatory chemicals linked to brain changes and dementia risk.

The latest findings are supported by several years of research. A large review published in Practical Neurology concluded that obesity is associated with smaller hippocampal volume, temporal lobe atrophy, mild cognitive impairment and increased Alzheimer's disease risk.
Some studies have suggested that obesity during midlife may nearly double the risk of developing Alzheimer's disease or dementia later in life.
Another review on obesity and aging reported that higher BMI is associated with poorer verbal memory, slower information processing and reduced executive function, particularly among older adults.
In January 2026, researchers also used genetic analyses to suggest that obesity and high blood pressure may directly contribute to dementia.
With a few lifestyle improvements, overweight and obese individuals can maintain a healthy BMI, reducing the risk of faster brain ageing and cognitive degradation. Experts recommend focusing on overall metabolic health rather than the number on the weighing scale alone.
Maintaining a healthy weight, regular exercise, controlling blood pressure, cholesterol and diabetes, following a Mediterranean diet, getting adequate sleep, remaining socially and mentally active can help maintain a healthy body weight.

Living with someone who has hepatitis can be worrying. People tend to immediately wonder whether they are at risk simply by sharing meals, hugging, or living under the same roof.
Fortunately, the answer depends on the type of hepatitis, and in most cases, everyday household contact does not spread the virus.
Dr. Shalimar, Prof. Department of Gastroenterology, AIIMS explains, "Hepatitis means inflammation of the liver. There can be many causes, but viral hepatitis is one of the most common. There are different hepatitis viruses, including A, B, C, D, and E. Some cause acute illness, while others can lead to long-term liver damage, including cirrhosis and liver cancer."
Experts say misinformation surrounding hepatitis often leads to unnecessary fear and stigma, causing patients to feel isolated. Understanding how different hepatitis viruses spread can help families protect themselves without avoiding normal interactions.
Dr Nanda Kishore M, Gastroenterology, Athulya Geriatric Care Hospital, answers our question, "No, Hepatitis is not a communicable disease that spreads through everyday contact such as hugging, holding hands, coughing, or sneezing."
For most forms of hepatitis, the answer is no. However, hepatitis B is spread through contact with infected blood and certain body fluids. Household transmission is possible, but it generally occurs when infected blood enters another person's bloodstream.
Possible household risks include sharing:

Dr. Kishore says that the mode of transmission largely depends on the type of hepatitis infected.
He says, "Hepatitis A and E are predominantly spread via means of contaminated food and water, while Hepatitis B and C are transmitted through infected blood and certain bodily fluids."
Hepatitis B is preventable by vaccine. Household members of someone with chronic hepatitis B are usually advised to get tested and vaccinated if they are not already immune.
Dr. Shalimar says, "For hepatitis B, current treatment controls the infection, and newer therapies under development offer hope for a functional cure in the future. Vaccination has dramatically reduced hepatitis B in many parts of the world. Expanding vaccination coverage remains one of the most effective ways to prevent the disease."
Living with a hepatitis infected individual is generally safe given that basic hygiene and recommended precautions are followed strictly. Understanding these facts helps reduce unnecessary fear and stigma associated with it.

Living with someone who has hepatitis does not mean you need to keep your distance. Instead, focus on practical precautions:
Dr. Ankur Jain, Associate Director & Unit Head, Gastroenterology, Hepatology & Endoscopy, Max Hospital, Dwarka, explains, "Hepatitis B and Hepatitis C continue to affect millions of people worldwide and remain major causes of liver cirrhosis and liver cancer. Individuals with a history of blood transfusions before routine screening, unsafe injections, or other risk factors should discuss screening with their physician.
He adds, "The liver has an extraordinary capacity to heal, but only if we identify problems early and address the underlying causes. Prevention, timely screening, and simple lifestyle modifications remain our most powerful tools in reducing the growing burden of liver disease in India."
