Insomnia is not being able to fall asleep, stay asleep, or get the benefits of sleep. This can lead to fatigue and other symptoms. Insomnia can be diagnosed as short-term, acute, or long-term, also referred to as chronic and can be its own disorder or a symptom of physical illness. Insomnia can occur at any age and can be caused by a number of items such as menopause, depression and anxiety, certain prescription medicines, stress, too much caffeine, drug abuse, chronic pain, and poor sleeping habits. There are both pharmaceutical and non-pharmaceutical treatments for insomnia. Your doctor can talk to you about what treatments might be appropriate for you.
