So indigestion is basically a constellation of symptoms that are all related to your digestive system. So basically it's pain, bloating, feeling full, more full than normal after a meal. All those together make up what's called indigestion.
It can be for a lot of different reasons, most likely from something you've eaten. There are times when you have a little bit more hyperacidity that can give you symptoms like that also.
Other symptoms that can, kind of, go into the category of indigestion could be acid reflux as well. And again it's where you're getting a lot of hyperacidity and that can cause some pain and some bloating and management of that is basically managing the symptoms.
You can get some bloating with indigestion and that could be the most uncomfortable feeling out of all the feelings, because it's just this sensation of a big balloon that's just expanding into your stomach. That can give you the feeling of early satiety, meaning you get full quicker or you just get more full than normal with a smaller amount of food.
In severe cases, people can change their diet. They can loose weight. They can get actually quite uncomfortable with the symptoms. So it's important to identify the cause of it and help manage those symptoms.
