Dilation
Dilation
Dilation (pronounced: /daɪˈleɪʃən/) is a term used in medicine to describe the process of enlargement, stretching, or expansion of a body part or organ. The term is derived from the Latin word "dilatare", which means "to spread out".
Types of Dilation
There are several types of dilation that can occur in the human body, including:
- Vasodilation: This is the widening of blood vessels, which decreases blood pressure.
- Bronchodilation: This refers to the expansion of the bronchial air passages in the lungs.
- Cervical dilation: This is the opening of the cervix during childbirth.
- Pupil dilation: This is the expansion of the pupil of the eye, often in response to changes in light or certain emotions.
Causes of Dilation
Dilation can be caused by a variety of factors, including:
- Stress: Stress can cause dilation of the blood vessels and pupils.
- Medication: Certain medications can cause dilation, such as those used to treat asthma or high blood pressure.
- Disease: Certain diseases, such as heart disease or lung disease, can cause dilation of the blood vessels or airways.
Treatment of Dilation
Treatment for dilation depends on the cause and the body part or organ affected. For example, dilation caused by disease may require medication or surgery, while dilation caused by stress may be managed through relaxation techniques or therapy.
