If you’ve ever struggled to go to the bathroom after a night of drinking, it’s probably not a coincidence. Alcohol affects many different bodily functions, including our digestive tract. In fact, the amount — and even the type — of alcohol we drink can cause problems with our bowel movements.
In this post, we’ll look at how alcohol causes constipation and what we can do to protect our digestive health. Let’s dive in!
Alcohol can cause constipation by affecting our digestive tract in several ways. Here are four of them:
One of the main ways alcohol causes constipation is through dehydration. Alcohol is a diuretic, which means it promotes water loss through urine. This is why we often have to urinate more frequently while drinking alcohol. But it’s also what leads to dehydration: we’re urinating more often, but we’re not taking in adequate fluids.
Whenever we’re dehydrated, our body pulls water from our intestines, making our stool hard and dry. This can make it more difficult to have bowel movement. Our body needs enough water to be absorbed by stool, and softer stool is easier to pass.
Alcohol can also slow down peristalsis, the process of moving food through our digestive system. When movement is slowed, we can become constipated. Certain types of alcohol can slow down peristalsis more than others. For instance, drinks with an alcohol content greater than 15% — such as liquors and some wines — tend to have an inhibitory effect on peristalsis.
On the other hand, beverages with lower alcohol contents — such as beer — can increase movement and lead to bowel movements. So, if you’ve ever wondered “does beer help with constipation?”, the answer is yes. Some types of beer, especially those that are unfiltered or made with a high amount of barley or wheat, can contain small amounts of fiber. Dietary fiber can help to increase stool bulk and promote regular bowel movements. Plus, the carbonation in beer can stimulate a bowel movement for some people. The bubbles can help to move stools through the digestive tract.
However, that’s not an excuse to drink more beer! All alcohol — including beer — does a number on our digestive health, not to mention many other parts of our body. So if we’re having constipation problems, probiotics, fiber, and hydration (with water) are a better way to go!
Alcohol also irritates our gut, causing inflammation in our intestinal lining. This can prevent the gut from effectively absorbing nutrients, which may lead to constipation. Similarly, alcohol can cause an overgrowth of intestinal bacteria, which can lead to symptoms like bloating and constipation.
Over time, alcohol can wear down the stomach lining, leading to stomach bleeding and gastritis. These complications can damage our health if they’re not addressed.
Some research indicates that alcohol can aggravate inflammatory bowel disease, such as Crohn’s disease or ulcerative colitis. These conditions cause intestinal inflammation that leads to pain and bouts of constipation and diarrhea.
One study found daily consumption of red wine resulted in increases in compounds that could cause an IBD flare-up. In general, alcohol weakens our immune system, boosts inflammation in the body, and can harm the protective barrier in our gut — all of which contribute to symptoms of IBD. However, more research needs to be done to understand the connection between alcohol and IBD.
Similarly, alcohol can also aggravate irritable bowel syndrome (IBS), a condition that causes abdominal pain, bloating, and changes in bowel movement. However, while some people feel their symptoms get worse when they drink alcohol, others don’t notice a difference. This is largely because everyone’s digestive system is different.
As noted above, some types of alcohol can actually trigger movement in our digestive tract and cause us to have bowel movements or loose stools. Beer, wine, and alcoholic beverages high in sugar or mixed with sugary juices can be particularly problematic, as sugar can be stimulating to our bowels.
Diarrhea is common for chronic heavy drinkers, but it can also occur when we drink too much in one sitting. This is largely because of fluid overload, as large amounts of alcohol prompt our intestines to release water.
Alcohol also agitates our intestines and causes them to react by speeding up digestion. The muscles in our colon contract more frequently, pushing stool out faster than usual. This quickening can lead to diarrhea, as the intestines don’t have time to digest nutrients properly. Needless to say, if we’re already experiencing an upset stomach or diarrhea, drinking alcohol can make our symptoms worse.
Because some types of alcohol can increase movement in our digestive track and lead to bowel movements, some of us — particularly long-term, heavy drinkers — might experience constipation if we stop drinking.
How long does constipation last after quitting alcohol? Unfortunately, there’s no definitive answer to that, as it varies from person to person. But drinking plenty of water, eating high fiber foods, and engaging in physical exercise can all help get our bowels moving.
In some cases, a doctor might recommend a mild laxative. But wait — is it safe to take laxatives after drinking alcohol? It’s generally okay to take a mild laxative once the alcohol is out of our system. This could be several hours or longer depending on how much we drink.
But we should avoid mixing alcohol with laxatives at the same time. This is because both alcohol and laxatives are metabolized by the liver, and they can interfere with one another. If we mix the two substances, we risk experiencing the negative side effects of both at the same time, such as dizziness, dehydration, drowsiness, and nausea.
What about dulcolax and alcohol? It’s generally advised that we avoid drinking alcohol while taking dulcolax, as it can increase the risk of side effects such as dehydration and low blood pressure. Always consult a doctor to discuss whether it’s safe to consume alcohol with any type of medication or over-the-counter drugs, including laxatives.
Cutting back on our alcohol consumption, or eliminating it entirely, is beneficial not just for our digestive tract, but for our overall health and well-being. Here are some other tips for preventing constipation and protecting our digestive health:
