These symptoms and signs may reflect dehydration from an infectious cause or adrenal insufficiency. The symptoms and signs could be the result of any infection or malignancy that causes high or prolonged fevers or decreased drinking and eating. They could also be the result of panic attack, anxiety, Parkinson's disease, hyperthyroidism, poisoning by alcohol or amphetamines, or a heart arrhythmia (bradycardia, tachycardia, including atrial fibrillation). Contact your doctor.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Parkinson's disease is a slowly progressive neurological disease characterized by a fixed inexpressive face, a tremor at rest, slowing of voluntary movements, a gait with short accelerating steps, peculiar posture and muscle weakness, caused by degeneration of an area of the brain called the basal ganglia, and by low production of the neurotransmitter dopamine. Most patients are over 50, but at least 10 percent are under 40.
Dehydration is the excessive loss of body water. There are a number of causes of dehydration including heat exposure, prolonged vigorous exercise, and some diseases of the gastrointestinal tract. Symptoms of dehydration include headache, lightheadedness, constipation, and bad breath. Treatment for dehydration is to replace lost fluids and electrolytes.
Stress occurs when forces from the outside world impinge on the individual. Stress is a normal part of life. However, over-stress, can be harmful. There is now speculation, as well as some evidence, that points to the abnormal stress responses as being involved in causing various diseases or conditions.
When sleepiness interferes with daily routines and activities, or reduces the ability to function, it is called "problem sleepiness." A person can have problem sleepiness without realizing it. Symptoms of problem sleepiness include: consistently don't get enough sleep, or poor quality sleep, fall asleep while driving, struggle to stay awake when inactive (like watching TV or reading), have difficulty paying attention or concentrating at work, school, or home, have poor performance problems at work or school, have difficulty remembering things, have slowed responses, have difficulty controlling your emotions, and/or if you have to take naps on most days.
