Cancer symptoms vary depending on many factors, such as the cancer type, stage, size and location. The early stages of cancer may not produce noticeable symptoms. As the disease progresses, symptoms often become more apparent.
Some general symptoms of cancer include: -Fatigue
-Unexplained weight loss/gain
-Change in appetite
Many symptoms share characteristics of other, non-cancerous conditions. If you experience any persistent symptoms or other changes in your health, it’s important to see a doctor as soon as possible.
Autonomic nerve disorders (dysautonomia) refer to disorders of autonomic nervous system (ANS) function. Dysautonomia is a general term used to describe a breakdown or abnormal function of the ANS. The autonomic nervous system controls much of your involuntary functions. Symptoms are wide-ranging and can include problems with the regulation of heart rate, blood pressure, body temperature, perspiration, and bowel and bladder functions. Other symptoms include fatigue, lightheadedness, feeling faint or passing out (syncope), weakness, and cognitive impairment.
Orthostatic intolerance refers to impairment in the body’s ability to handle gravity. When a person stands, blood pools in the abdomen and legs. Normally, the autonomic nervous system will compensate by constricting blood vessels and pushing the blood to the brain. When autonomic pathways are damaged, these reflexes, termed baroreflexes, do not function adequately. As a result, the person becomes dizzy, light-headed, and may faint. In addition, digestion is controlled by the autonomic nervous system. When the ANS malfunctions, the “victim” commonly develops gastrointestinal problems. Symptoms include nausea, bloating, vomiting, severe constipation, and abdominal pain.
