Bad breath, or halitosis, in children is often the result of bacteria building up between teeth or on the back of the tongue. In other cases, certain foods that your child eats, sinus conditions, improper dental hygiene or an underlying medical condition might be the culprit.

A high-protein, low-carb diet can put your body into ketosis -- a state where your body is burning fat instead of glucose for energy. When you limit your carb intake, your body has to use stored fat for energy, which can be a short-term way to lose a few pounds.

Commonly called halitosis, bad breath is related to various conditions, including issues with the sinuses. It often arises after eating certain kinds of food, which can also make the situation worse, no matter what the underlying cause is, according to the Cleveland Clinic.

Bad breath can be embarrassing, and the person with the condition may not know he has it. Bad breath can be caused by several factors, including an infection in the throat. Uncontrolled, a throat infection can lead to even worse symptoms than strong odor.

Shallow breathing can be an alarming and potentially life-threatening symptom if left untreated. People who develop shallow breathing can generally develop wheezing and blue skin (cyanosis). Sometimes, shallow breathing can be due to fluid accumulation within the lungs.

Bad breath is one of the potential symptoms of a tooth infection, explains the National Institutes of Health. The foul or offensive odor is usually a result of a tooth abscess, which is often characterized as a collection of pus caused by tooth decay.

Rapid breathing, often described as panting, is quite common in newborns. When no other symptoms are present--and rapid breathing comes and goes and the baby appears otherwise healthy and comfortable--there's usually no cause for concern.

Contrary to popular belief, your bad breath may have little to do with your oral hygiene. If you brush and floss regularly and continue to fight against halitosis, you may be pleased to know that there are several vitamins that help bad breath.
