Hyperactivity is a state of being unusually or abnormally active. It is often difficult to manage for people around the person who is hyperactive, such as parents, employers, and teachers. If you have hyperactivity, then you have a chance of becoming depressed or anxious due to your condition and how people respond to it .
The most common characteristics of hyperactivity include: being easily distracted; impulsive behavior; aggressive behavior; constant movement. If you are struggling to stay still or concentrate, then you can develop other problems as a result of it.
Some examples can include: increase the risk of alcohol and drug abuse; lead to accidents and injuries; strain relationships with friends and family; lead to difficulties at school or work. Hyperactivity is often a symptom of an underlying mental or physical health condition. ADHD (Attention Deficit Hyperactivity Disorder) is one of the main conditions associated with hyperactivity. 
This condition is causing you to become impulsive, inattentive, and overactive. Usually, it is diagnosed at a young age, but in some cases, the first diagnosis can be given to people when they are adults. You need to remember that the hyperactivity is treatable. Early detection and treatment are important for the best results.
If the hyperactivity is left untreated, then it can disrupt your work, school, and personal relationships. Also, it can be a sign of an underlying condition that requires treatment. You need to remember that the early diagnosis of hyperactivity can help you or your child to have a successful treatment. Also, your doctor may refer you to a specialist for care.

Hyperactivity is a state of excess activity that can be manifested by symptoms, such as excessive movement, nervousness, jumpiness, or fidgeting. The hyperactivity is often accompanied by difficulty concentrating or focusing on a task, difficulty remaining quiet in school, or excessive talking. But, it is very important to distinguish true hyperactivity from the active and impulsive behaviors that are exhibited by normal children.
If you are distressed about experiencing hyperactivity, then you may develop depression or anxiety . There are many cases, when adults who experience hyperactivity, showed signs of it as children. If you or your child experiences some of the above-mentioned symptoms of hyperactivity, then you need to talk with your doctor. Your doctor will ask about the symptoms that you feel and you need to tell him or her when your symptoms began.
Also, your doctor will ask you about the changes in your overall health and about any medications that you might be taking. You need to answer these questions to your doctor, so he or she can determine the type of hyperactivity that you are experiencing. This can help your doctor to determine if the hyperactivity is caused by a new or existing condition or it is a side effect of medication.
Also, your doctor can take a blood or urine sample to check your hormone levels. This can help your doctor to learn if you have a hormonal imbalance. There are some cases when the hormonal imbalance can be a cause of hyperactivity. It is very important to get a proper diagnosis, so your doctor can give you the right treatment.
