There are many factors that can contribute to stomach pain. This article will explain a few causes of stomach aches, as well as provide you with some simple remedies.

Causes of Stomach Aches

Aches and pain in your abdomen are more common than you would think. In fact, researchers have found that at least 30% of people suffer from this type of ache and although it isn’t technically defined as a disease, it is a slight defect in the digestive system.

The intensity of the pain you feel will determine how serious the stomach ache is. However, if you find that you suffer from these pains quite often and experience some of the other symptoms mentioned below, you should see your doctor. Let’s take a closer look.

What factors are associated with stomach aches?

1. Nerves

Sometimes, anxiety or stress can build up in your second brain, which is your stomach. Nerves are almost always concentrated in this part of your body, and they can have a negative effect on your digestion, causing heartburn or even diarrhea.

So, don’t worry if you experience this type of problem from time to time, because it’s probably just the result of stress. However, now that you know where your stomach aches may be coming from, you should try to manage your anxiety levels to avoid more severe discomfort.

2. Gas

This is one of the most common causes of stomach aches. Poor digestion and certain foods can cause irritating stomach gas. These are usually concentrated in the pit of your stomach, just below your ribs. They can cause you to feel sharp pains, especially when you take deep breaths.

3. Heartburn

Gastric reflux and heartburn are also very common ailments that start with stomach pain in the upper part of the stomach. Acids naturally move upwards, meaning that this pain is concentrated in your esophagus, which is found above your digestive system.

4. Irritable bowel syndrome

Intestinal inflammation is one of the more complicated causes of stomach aches. It falls into the category of organic dyspepsia, which is when your digestive system suffers from a disease.

If you have diarrhea or suffer from constipation, vomiting and intense pain on a regular basis, you should see your doctor right away. Irritable Bowel Syndrome (IBS) can masquerade as other conditions and vice versa, so it’s important to get a proper diagnosis from a medical professional.

5. Certain medications

Causes of stomach aches include medications such as ibuprofen

If you take iron supplements or if you have recently taken ibuprofen, for example, you will likely feel some stomach pain. These medications cause you to feel a slight burning in your stomach that lasts for a few hours. It’s nothing too serious, but it is quite bothersome.

6. Eating too quickly

Remember, in order to properly digest your food, you should always try to eat slowly, thus exposing your food to greater quantities of saliva. This element of your digestive system is necessary in order for your previously chewed food to mix together. If you eat too quickly, you will likely end up with a stomach ache.

7. Ulcers

Does your stomach hurt whenever you eat certain foods? Especially when those dishes are heavily seasoned or spicy? Do you suffer from frequent vomiting? Do you ever find blood in your vomit? If you answered yes to these questions, you should see your doctor right away, because you may have an ulcer.
