How Can Consumption of Alcohol And/or Caffeine Lead to ECF

Question

How can consumption of alcohol and/or caffeine lead to ECF hypertonicity?​
A)​They stimulate adrenal hormone secretion.
B)They inhibit adrenal hormone secretion.
C)They inhibit vasopressin secretion.
D)They stimulate vasopressin secretion. 
E)​They slowly destroy the hypothalamus.

Accepted Answer

Both alcohol and caffeine are diuretics, meaning they increase urine production. This can lead to dehydration and a decrease in total body water, resulting in an increase in electrolyte concentrations in the extracellular fluid (ECF) and hypertonicity. Vasopressin, also known as antidiuretic hormone (ADH), helps regulate water balance in the body by increasing water reabsorption in the kidneys. However, alcohol and caffeine can inhibit vasopressin secretion, exacerbating the hypertonicity.
