A lot of our body’s functions depend on when we are defecating and how well our bowel movements are taking place. People have different pooping habits, with some people having a nightly routine and others enjoying a morning bathroom run. But is it normal for one to run to the bathroom after every meal? Not only is it inconvenient but it could be a sign of something going wrong with your body. Have you ever enjoyed a meal and immediately needed to use the restroom?
If so, you might be worried that something is wrong with you. But you don’t need to stress about this! It is actually quite common and doesn't necessarily indicate a health problem.
This phenomenon is called the gastrocolic reflex. When food enters your stomach, it triggers a series of signals in your digestive system. Your stomach stretches to accommodate the food, and sends signals to your brain through the vagus nerve. The brain then communicates with your large intestine, telling it to make room for the new food by moving its current contents along. In other words, you're not pooping out what you just ate, but what has been in your digestive system for a day or two.

Frequently experiencing deep sleep may help prevent the development of brain changes related to Alzheimer's Disease, the most common form of dementia.
Researchers from the University of California, Berkeley, Stanford University, and UC Irvine in the US have found that people experiencing early symptoms of Alzheimer's performed better on memory function tests as they got more deep sleep.
This sign was found to be independent of education and physical activity, two factors, along with social connection, known to contribute to cognitive resilience in older age.
Those with similar Alzheimer's-linked changes who failed to get as much deep sleep did not do as well on the same tests. By comparison, sleep made little difference to those individuals with few Alzheimer's-related deposits.
The results imply that a frequently being able to sleep deeply frequently could help support the memory decline that sets in as dementia begins to take hold.
UC Berkeley neuroscientist Matthew Walker said of the results: "Think of deep sleep almost like a life raft that keeps memory afloat, rather than memory getting dragged down by the weight of Alzheimer's disease pathology.
"This is especially exciting because we can do something about it. There are ways we can improve sleep, even in older adults."
Previous research has also shown that poor sleep is both a risk factor for and a symptom of Alzheimer's disease, making it tricky for scientists to detect how sleep is linked to neurological damage.
What Is Alzheimer’s Disease?Alzheimer's disease is one of the most common forms of dementia and mostly affects adults over the age of 65.
About 8.8 million Indians aged 60 and above are estimated to be living with Alzheimer's disease. Over seven million people in the US 65 and older live with the condition and over 100,00 die from it annually.
Alzheimer's disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate in the brain and damage cells responsible for memory.
Amyloid protein molecules stick together in brain cells, forming clumps called plaques. At the same time, tau proteins twist together in fiber-like strands called tangles. The plaques and tangles block the brain's neurons from sending electrical and chemical signals back and forth.
Over time, this disruption causes permanent damage in the brain that leads to Alzheimer's disease and dementia, causing patients to lose their ability to speak, care for themselves or even respond to the world around them.
While there is no clear cause of Alzheimer's disease, experts believe it can develop due to genetic mutations and lifestyle choices, such as physical inactivity, unhealthy diet and social isolation.
Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Over time, Alzheimer's disease leads to serious memory loss and affects a person's ability to do everyday tasks.
There is no cure for this progressive brain disorder and in advanced stages, loss of brain function can cause dehydration, poor nutrition or infection. These complications can result in death.
The blood test, known as Lumipulse, can detect amyloid plaques associated with Alzheimer’s disease and has proven to be a “less invasive option” that “reduces reliance on PET scans and increases diagnosis accessibility.”
FDA Commissioner Martin A. Makary said of the landmark decision, "Alzheimer’s disease impacts too many people, more than breast cancer and prostate cancer combined.
"Knowing that 10 percent of people aged 65 and older have Alzheimer's, and that by 2050 that number is expected to double, I am hopeful that new medical products such as this one will help patients."
It remains unclear when this test will be available for commercial use across the world.

Think you aged overnight or have you been seeing more signs of aging recently?
According to an August 2024 Nature Ageing study on molecular changes associated with ageing, humans age significantly twice in their life, once at an average age of 44 and the other at around age 60.
Geneticist Michael Snyder of Stanford University explained: "We're not just changing gradually over time; there are some really dramatic changes. It turns out the mid-40s is a time of dramatic change, as is the early 60s. And that's true no matter what class of molecules you look at."
The study found that about 81 percent of all the molecules they studied showed changes during one or both of these stages. Changes peaked in the mid-40s, and again in the early 60s, with slightly different profiles.
The mid-40s peak showed changes in molecules related to the metabolism of lipids, caffeine, and alcohol, as well as cardiovascular disease, and dysfunctions in skin and muscle.
The early 60s peak was associated with carbohydrate and caffeine metabolism, cardiovascular disease, skin and muscle, immune regulation, and kidney function.
However, the study authors noted that more granual research was needed to understand how the ageing process works at these peak ages.
Mariana Rodrigues, a PhD student at NYU School of Global Public Health and the first author of the study, said: "Our research suggests that subjective experiences may be driving objective measures of aging. Aging-related anxiety is not merely a psychological concern, but may leave a mark on the body with real health consequences."
"We know from previous research that anxiety, depression, and mental health in general are associated with a number of physical health outcomes, but until now researchers haven’t focused on whether there is a correlation between worrying about aging and the process of aging itself.
“Women in midlife may also be multiple in roles, including caring for their aging parents. As they see older family members grow older and become sick, they may worry about whether the same thing will happen to them".
After analyzing data from 726 women, the researchers while worrying about declining health, had the strongest associations with biological aging, anxiety about declining attractiveness and fertility were not significantly associated with it.
They theorized that this may be because research shows that health-related concerns are more common and persist over time, while worries about beauty and reproductive health may fade with age.
“Aging is a universal experience,” said Rodrigues. “We need to start a discourse about how we as a society—through our norms, structural factors, and interpersonal relationships—address the challenges of aging.”

Dehydration is a serious concern for people fasting during the month-long Ramadan period, and can severely impact kidney and prostate health. Experts suggested that avoiding excess salt and caffeine can help.
While Ramadan fasting is generally safe for people with early-stage chronic kidney disease (CKD), maintaining adequate hydration between iftar and sehri -- the two important meals each day for faithful observing the fasting -- is of significant importance.
Dehydration can lead to acute kidney injury and electrolyte imbalances for individuals with advanced CKD. As prolonged fasting hours -- more than 12 hours a day -- urine becomes concentrated, increasing the risk for kidney stones and Urinary Tract infections (UTIs).
For men with prostate problems, fasting during Ramadan can pose challenges, such as Benign Prostatic Hyperplasia (BPH) or an enlarged prostate, primarily due to dehydration.
“As a practicing urologist and kidney transplant surgeon in India, I often notice a rise in kidney stone pain and urinary infections during Ramzan. When patients fast for long hours -- especially in our warm climate -- urine becomes highly concentrated. That increases the risk of stones and UTIs. Men with prostate enlargement sometimes report worsening urinary flow because they consciously reduce fluid intake,” Dr. Pankaj Panwar, Additional Director, Urology, Fortis Escorts Okhla, New Delhi, told HealthandMe.
The doctor advised people “to hydrate strategically between Iftar and Sehri, avoid excess salt and caffeine”.
Consuming high-sodium foods such as processed meats, pickles, salty snacks, and fast food during iftar or sehri can increase thirst and dehydration.
High salt intake forces the body to pull water from cells to dilute the sodium, leading to severe thirst. It can also lead to bloating.
Similarly, caffeine in coffee, tea, chocolate, and energy drinks can be diuretic and cause the body to lose fluids and salts through increased urination. Particularly, drinking coffee or tea at sehri -- the pre-dawn meal -- can lead to faster dehydration during the day.
Caffeine consumption, especially late in the evening, can also interfere with sleep, making it harder to wake up for sehri.
“Ramzan is a sacred month of fasting, but prolonged abstinence from water, especially in hot climates, can increase dehydration risk. Concentrated urine puts stress on the kidneys and may worsen kidney stones or trigger urinary tract infections,” Dr. Mangesh Patil, Urologist at Saifee Hospital, Mumbai, told HealthandMe.
Dehydration during Ramadan fasting can lead to symptoms like headaches, extreme thirst, fatigue, and dizziness. But in case of severe dizziness, fever, confusion, or blurred vision, the experts warned of immediate medical help.
“Do not ignore warning signs like flank pain, fever, or difficulty passing urine. A little planning can prevent an emergency hospital visit,” Panwar said.
Patil said warning signs include severe flank pain, burning urination, fever, vomiting, blood in urine, or reduced urine output. Men with Benign Prostatic Hyperplasia may notice worsening urinary symptoms.
