Signs of an unhealthy gut
The balance of "good" and "bad" bacteria can be affected by factors such as illnesses, diet change or lifestyle changes.
Here are possible signs of an unhealthy gut:
1. Upset stomach
- Having poor gut health affects your body's ability to process food well. Some signs of an upset stomach include:
- Bloating
- Constipation
- Diarrhoea
- Heartburn, which is a painful or burning feeling at the chest or throat area. It happens when the acid from stomach goes back up the throat.
2. Gaining or losing weight without changes to your diet or exercise habits
- An unhealthy gut may reduce the body’s ability to take in nutrients, control sugar levels in the blood and store fat.
- When the body is unable to take in nutrients well because "bad" bacteria builds up in the gut, weight loss can happen.
- On the other hand, an unhealthy gut can also affect the way insulin works in the body. Insulin is a hormone in our body that helps to control our blood sugar. Over time, this results in a state known as insulin resistance, where insulin stops working well, and this can cause weight gain.
3. Poor sleep or constant tiredness
