Ketosis and bad breath can occur during a low-carb diet due to the presence of ketones, which aid in metabolism and digestion. Dehydration and lack of saliva can also contribute to bad breath. Diabetics may experience ketosis and bad breath when the pancreas fails to produce enough insulin. Ketosis can be tested through urine strips and may cause headaches, dizziness, fatigue, and insomnia.
Ketosis and bad breath are side effects of a low-carb diet and could occur in diabetics when the pancreas fails to create enough insulin. Your breath may smell sweet or fruity when you restrict carbohydrates due to changes in your metabolism. Ketosis and breath-related concerns stem from the presence of ketones, chemical molecules that produce acetone, defined as a waste product excreted through the lungs and urine.
Ketones regulate the body’s pH balance and metabolism. These chemicals aid in the digestion of nutrients from food and store excess carbohydrates as fat. When a diet restricts carbohydrates, ketones are released by the liver to begin converting fat and protein into energy. This process is called ketosis and your breath is affected as acetone leaves your lungs through your breathing.
Another relationship between ketosis and breathing could come from the fact that the body uses more water when metabolism changes. A person may become dehydrated, causing less saliva to form in the mouth. Without enough saliva, bacteria levels could rise, leading to bad breath.
Ketosis and bad breath typically resolve within a few weeks after fasting or starting a low-carb diet. Some dieters use breath mints or sugarless gum to mask the unpleasant odor. Increasing your fluid intake might help, along with chewing on fresh parsley sprigs. The condition is not related to dental hygiene, but to an overabundance of acetone in the lungs.
Diabetics might experience ketosis and bad breath when not enough insulin is produced by the pancreas. This hormone allows cells to absorb glucose, a simple sugar obtained from carbohydrates, to be used as energy. If glucose can’t be absorbed, it stays in the blood, causing the body to release ketones to convert proteins and fats into energy. Prolonged ketosis in diabetic patients could lead to coma and death from excess blood ketones.
Ketosis can be tested through urine strips that turn purple when ketones are present. This typically indicates that the body is using fat for energy. Some dieters experience headaches or dizziness along with ketosis and breathing problems at the beginning of the diet. You may also experience fatigue and insomnia. The level of ketosis and bad breath depends on how severely the diet restricts carbohydrates.
