Our bodies sometimes make noises that we don't have any control over, but there are 10 specific sounds that we don't want to hear ourselves making – particularly at night.

Under normal circumstances these are involuntary and nothing to worry about. But there are tell-tale signs which could indicate something is wrong. It is therefore worth listening when your body squeaks and rumbles throughout the day and knowing what the sounds are actually trying to tell you.

Some weird noises mean and you need to see a doctor immediately others are less concerning. Examples include hearing a loud banging sound as you fall asleep, your heart thumping in your ears and pops and crackles in your joints.

1. Growling in your stomach

A natural assumption when you hear grumbles and gurgling in your stomach is that it is because of hunger. Known as borborygmi, these noises are a way of alerting you your stomach it wants a meal. But it may also growl after you've eaten. Harvard Health says this shows your intestines are sending liquid and food through your digestive tract.

William Chey, coeditor-in-chief of the American Journal Of Gastroenterology says the 'gastrointestinal tract' makes noisy contractions every few hours to clear out leftover debris between meals. It results in sounds which show your gut is doing its jobs and operating as it should. However, if normal stomach noises also bring pain, swelling or fever, it could mean a stomach infection and is time to see your doctor.
