A high level of carbon dioxide in the blood may indicate conditions such as Cushing's syndrome or hyperaldosteronism, according to MedlinePlus. Those who have breathing disorders or who have been vomiting may also have high levels of carbon dioxide in the blood.
Cushing's syndrome is a condition that is caused by too much cortisol in the body, explains WebMD. Common symptoms of this disorder include upper body weight gain, a fatty pad in the lower neck, thin legs and arms, and a round, rosy face. Other symptoms of Cushing's syndrome include acne, weak muscles, high blood pressure and kidney problems. The main treatment for Cushing's syndrome is surgery, as it is often caused by a tumor on the adrenal glands or pituitary gland. Doctors may also attempt to shrink the tumor with medication or radiation.
Hyperaldosteronism is a condition where the body makes too much aldosterone, a hormone from the adrenal gland, claims MedlinePlus. The most common symptoms of hyperaldosteronism include headaches, fatigue, numbness and muscle weakness. Some people with hyperaldosteronism also experience paralysis that comes and goes. Since this condition is often caused by a tumor on the adrenal gland, the main treatment for hyperaldosteronism is surgery to remove the tumor. Some people may find that limiting salt intake and taking medications may also control hyperaldosteronism.
