Hypertension, diabetes, hyperlipidemia, fatty liver, hyperuricemia, gout and obesity etc.
Hypertension will cause the damage of blood vessel, heart and kidney. The effects of hydrogen in lowing blood pressure may not be obvious in short time, but hydrogen inhalation can reduce the damage that caused by hypertension to other organs.
Diabetes causes many complications, many of which are fetal. Hydrogen can help body avoid serious organs problem such as blindness, foot ulcers and kidney failure when blood glucose is unstable or very high.
Hyperlipidemia will cause great damage to blood vessel. Hyperlipidemia and diabetes are the leading causes of arteriosclerosis, stroke and myocardial infarction.
Fatty liver is apt to cause hepatitis, cirrhosis, even liver cancer. The effects of hydrogen on hyperlipidemia and fatty liver are very obvious and has no side-effect on other organs.
Medicines used for the treatment of hyperuricemia and gout, like probenecid, are very harm to liver and kidney and should not be used for a long time. Hydrogen inhalation can relieve the pain caused by hyperuricemia and gout to human body and have no adverse effect.
Obesity is a major cause of diabetes, hypertension, fatty liver and tumour.  Hydrogen can boosts fat consumption while improving the state of human cell.
