Why do anxious feelings create the need to go to toilet frequently?

Feeling anxious may cause you to have stomach cramps, which could result in the need to go to the bathroom frequently.

Anxiety increases the metabolic rate in the body, temporarily. So that may affect digestion of food as well.

I believe it may be due to the fact that your digestive system is very fragile and any slight changes to you can cause changes to it. It may also be because when we're feeling anxious, the stress from that feeling can cause us to enter 'fight or flight' mode which different people handle different ways. Some people sweat, others shake, some people need to go to toilet. There is also the possibility that IBS is involved, it may be a good idea to get that checked out just to be safe.

A lot of time anxiety is linked to our desire to control something or a situation. In most cases, we have the ability to control our bladders, and knowing where the nearest bathroom is is another part of that control. I find that when dealing with anxiety, holding onto things that we can control (or feel we can) can actually be helpful. If it is causing you distress, it may be worth looking into further and working to develop different means of control.

Anxiety creates a lot of pressure on your body and your hormones and affects your digestion system. It is very common for people with anxiety.

Sometimes you may become frightened and this will result in the need to use the bathroom. This is common when experiencing anxiety.

Anxiety triggers physical symptoms in people including nausea and stomach pains at times. These are caused by the chemicals in your brain that are produced when you are in an anxious situation. So, even though having to go to the bathroom more sucks, it is a completely normal reaction to anxiety.

When your body is stressed, it goes into a flight or fight response. The flight response can cause your body to have the shakes, cause you to feel nauseous, dizzy, accelerated heart rate, faint, etc. When your body is in it's flight response your body is working twice as hard because it thinks its in trouble and is trying to protect you. In this case, frequent trips to the bathroom is a just a normal response to your body's stress levels.

So when one has IBS on occasion, how bad can things turn out? Can it get to the point of creating an ulcer in the colon? I do have a terrible pain in the abdominal area, is that a hint? I’m supposed to have an endoscopy soon, because there’s that pain, but I’m also worried it can be worse.

Anxiety can cause discomfort in your stomache and other physical discomfort. This can cause gastrointestinal issues and make an anxious person go to the restroom more frequently.
