8. You may have liver problems
If you notice that your breath smells fishy, particularly if you haven’t eaten fish recently, then there could well be a problem with your liver. It may even signify that you have liver failure, so it’s a serious thing to notice.
If you find that your breath smells like this, even when you brush regularly and eat well, then you should definitely speak to your doctor. A number of tests can help you determine whether there is a problem or not, so don’t be afraid to go and see a medical professional about this so you can rule out this problem – or deal with it if you do have an issue.
