Many times a sleep disorder can be caused from an illness or from the medications used to treat an illness. Some of the common health conditions that can cause a sleeping problem are cardiovascular disease, endocrine disorders, neurological disorders, respiratory disease, mental illness, gastroesophageal reflux disease, kidney disease, and arthritis.
Cardiovascular disease includes congestive heart failure and coronary artery disease. These are the two most common heart problems that affect sleep and can cause a sleep disorder. Congestive heart failure occurs when the heart can no longer pump enough blood fo the body's needs. Blood backs up in the veins of the heart which lead to the kidneys and edema eventually damages the lungs and other organs. People suffering from congestive heart failure have a very high risk of developing the sleep disorder of obstructive sleep apnea. Coronary heart disease is the build up of fatty deposits in the arteries that supply blood to the heart, called atherosclerosis. This condition also can lead to obstructive sleep apnea.
Sleep disorders can occur from endocrine disorders such as diabetes and thyroid disease. Diabetes is a disease that affects the way the body processes and uses carbohydrates, fats and proteins. People that have uncontrolled diabetes often develop the sleep disorder of restless leg syndrome. Thyroid hormones regulate the body's energy levels. Hyperthyroidism can make it difficult to fall asleep, and cause night sweats the person to wake.
Neurological disorders include Parkinson's disease, Alzheimer's disease, epilepsy, and strokes. Parkinson's disease is a central nervous system disorder. This disease causes problems with body motion, including tremors, unstable posture, slowed body movements, muscle stiffness, and difficulty walking. Sleep disorders that occur with this disease include REM sleep behavior disorder and sleep onset insomnia. Alzheimer's disease impairs the brain's intellectual functions and is the most common cause of dementia. This disease causes sleep fragmentation. Epilepsy causes recurrent, sudden, brief changes in the normal electrical activity of the brain. People with this condition are twice as likely to suffer from the sleep disorder insomnia. People that suffer a stroke usually also have obstructive sleep apnea.
People that have respiratory diseases, such as asthma and chronic obstructive pulmonary disease,
usually also have a sleep disorder. Asthma is a chronic lung condition that makes breathing difficult when air passages become inflamed and narrow. Chronic obstructive pulmonary disease, known as COPD, refers to a group of disorders that damage the lungs and make breathing difficult. Many people with these conditions suffer from insomnia and sleep fragmentation.
Mental health problems, such as depression, anxiety, schizophrenia, bipolar disorder, and seasonal affective disorder can also lead to a sleep disorder. People with these mental health disorders often suffer from sleep fragmentation and insomnia.
Gastroesophageal reflux disease, known as GERD, causes the stomach's juices to flow backwards into the esophagus. This causes the sleep disorder of sleep fragmentation.
Kidney disease causes the kidneys to lose their ability to filter the proper amount of waste products from the blood and regulate the body's balance of salt and water. This can cause the sleep disorders of restless leg syndrome and insomnia to develop.
People with arthritis often find it difficult to fall asleep because of the pain. This often results in insomnia.
If an illness causes a sleep disorder to develop, the sleep disorder is secondary to the illness. Successful treatment of the primary underlying cause will usually diminish the effects of the sleep disorder.

Most people don't realize they oversleep when they have a condition called hypersomnia and that's due in part to recurring episodes of excessive daytime sleeping and prolonged nighttime sleep. This is different from the average person taking that midday nap when they do it at sometimes the most inappropriate times like at work, during meals, or even in conversation with people.
Hypersomniacs are also diagnosed with narcolepsy, which can be quite dangerous because some individuals are behind the wheel of cars or even cooking in their home and aren't aware that they fell asleep. Some hypersomniacs and narcoleptics can fall asleep and then wake up and resume where they left off in conversations with people. Usually daytime naps usually provide no relief or symptoms to the problem(s) and will result in the individual(s) having increased difficulty in waking from a long extended period of sleeping, disorientation, anxiety, decreased energy, increased fatigue, restlessness, slow thinking, slow speech, loss of appetite, hallucinations, and problems with memory functions.
Some individuals also experience losing the ability to function in normal family, social, occupational, and other settings familiar to that person.
Hypersomnia can be triggered by sleep apnea or narcolepsy, where it can lead to dysfunction of the autonomic nerve system, which can be brought on, by acute alcohol and/or drug abuse. In some cases rare or not it can also be triggered from physical problems such as tumors, head trauma or injuries to the nervous system. Specific medications or withdrawal of medications and/or drugs may contribute to someone having hypersomnia. Medical conditions such as multiple sclerosis, depression, encephalitis, epilepsy, and obesity can contribute to hypersomnia as well.
It's also been noted that those who have hypersomnia are also genetically dispositioned to this problem whereas in others there's no known or documented cause. Hypersomnia typically affects adolescents and young adults in their 20s and 30s. Although the most common causes of this disorder differs in the age brackets. Information can be located on the National Institute of Neurological Disorders and Strokes website if you're seeking a more thorough clinical explanation to this problem. This isn't a substitute for medical advice from a licensed physician so it's ideal to educate yourself, but leave the diagnosing and treatment to a doctor so that you condition can be monitored closely.
People who are not seeing a doctor when they identify problems that are not normal for them to experience are misdiagnosing too many issues with sleep. Persons who are severely obese can also have a difficult time losing the weight because of the fact that lack of sleep can increase the body's metabolic rate, which can trigger excessive hunger in those who are trying to lose weight.
This is why so many people who are obese are eating more than they should because a lot of them sleep so much that they wake up wanting to eat when they should be sleeping like normal people do and not up at all hours of the night wanting to eat. This is why it's harder for people who are obese to lose weight when they sleep too much and not training their body to rest instead of wanting to eat food.
