Ketone bodies are products of the breakdown of fatty acids and are generally stored in the liver as a storage vehicle for a variety of tissue fuels and are physiologically important for vital signs. However, women in pregnancy and diabetic patients often experience excessive urinary ketone bodies. If left unattended, this may lead to flatulence and digestive dysfunction, usually with nausea, vomiting, and in severe cases, vomiting of blood, abdominal distention, dizziness, and even fainting. If once high ketone bodies occur, it means that it becomes difficult for sugar to be broken down in the body, resulting in excessive fat breakdown, usually during intense exercise or prolonged starvation conditions. Diabetes mellitus, with impaired pancreatic secretion, can also cause high ketone bodies, especially for severe diabetes mellitus, which can be preceded by ketoacidosis at an advanced stage. It is important to ensure that the gastrointestinal system is normal on a daily basis, to avoid infections and viruses, to have a regular diet, not to be hungry and full, to have a balanced diet, and to eat more meals and less food. Mentally relax, avoid overexertion and excessive concentration, learn to reduce stress and shift emotions. If there is a persistent high temperature, it is necessary to cool down in time to avoid complications. Ketone bodies in general at normal levels are not harmful to the human body, but when their values are too high, with painful urination and blood in the urine, they may cause damage to the urinary system and functional disorders of the digestive system.
