Final answer:
Postural hypotension and salt craving can be symptoms of Addison's disease, which is due to hypofunction of the adrenal cortex. Effective treatment often requires addressing the underlying condition, and may include increasing salt and fluid intake.
Step-by-step explanation:
Postural hypotension, also known as orthostatic hypotension, is a condition where blood pressure drops significantly upon standing up from a sitting or lying position, often leading to dizziness or fainting. One of the diseases associated with postural hypotension and salt craving is Addison's disease. This condition is due to hypofunction of the adrenal cortex, which leads to insufficient production of corticosteroids. There are several reasons why postural hypotension occurs, including low blood volume, ineffective sympathetic reflex, or autonomic failure. For instance, in Addison's disease, sufferers may experience low blood glucose levels, low blood sodium levels, and cravings for salty foods. Addressing the underlying condition, such as improving blood glucose control in diabetes, can help manage the symptoms of postural hypotension. Increasing fluid and salt intake may also alleviate postural hypotension in some cases. It is crucial for individuals experiencing symptoms such as dizziness upon standing, significant salt cravings, or any other signs associated with Addison's disease to seek medical attention for proper diagnosis and treatment.
