Supposedly the average person expels gas between 10 and 25 times per day, but that seems rather high. In any case, it's worse for old people they say. Supposedly people fart more often as they age. However, there was actually a study done in 2017 and it was found that older adults don't necessarily pass gas more frequently than younger adults, at least the old people didn't admit to it. In spite of the survey, some older people do and there are real reasons why. As you get older, you're more likely to take medications, gain weight, become lactose intolerant and have other issues that lead to an increase in gas. The actual age at which one becomes a serial farter is variable, in part due to different medical conditions, medications and genetic makeup.
Americans tend to gain weight as they age. It's due to such things as decreased metabolism, increased medications which can cause weight gain and decreased exercise. Such things can lead to increased acid reflux and belching and...increased flatulence.
Medication for high blood pressure, type 2 diabetes or heart disease tend to cause constipation, which often results in retention of gas. Prescription medications also tend to cause weight gain, which can worsen gastro-esophageal reflux disease.
A common cause of bloating and flatulence is dairy products and lactose intolerance increases as we age...something to d with having less lactase enzyme that helps us digest lactose.
It's an unpleasant thought, but as we age the anal sphincter weakens with the resulting lowered ability to hold in flatulence. Some people like to blame old men for farting a lot, but the fact is, old women are worse especially if they have delivered a lot of babies.
Stopping flatulence depends on what's causing it. A sensitivity to lactose means avoiding dairy products by substituting oat milk, for example or taking lactase replacement enzymes.
Again, it's unpleasant to discuss, but in the case of a weakened anal sphincter, Kegel exercises can strengthen your pelvic floor muscles, some of which supply the anal sphincter.
Cruciferous veggies, such as
Brussels sprouts, broccoli and cabbage and vegetables that contain
fructose, such as onions and asparagus, can cause gas so avoiding them can also help cut down on flatulence.
Avoiding lying in a supine position for at least two hours after eating can also help. It's also recommended that food be eaten slowly and chewed carefully. The avoidance of gulping water and drinking carbonated beverages will also help.
Over-the-counter products containing simethicone and a product called Beano can help with reduce bloating and gassiness caused by one's diet.
But, the question remains, "Why would one want to reduce flatulence?" Farts are fun.
