Endocrine System

<p>Decreased thyroid function due to aging, also known as hypothyroidism, is a condition where the thyroid gland does not produce enough thyroid hormones.</p> <p>Thyroid hormones regulate the body&rsquo;s metabolism, temperature, and other functions.When there is not enough thyroid hormone, the body&rsquo;s processes slow down and cause various symptoms.</p> <p>Some of the symptoms of hypothyroidism in the elderly are:.</p> <p>&bull; Fatigue.</p> <p>&bull; Weight gain.</p> <p>&bull; Cold intolerance.</p> <p>&bull; Constipation.</p> <p>&bull; Dry skin.</p> <p>&bull; Hair loss.</p> <p>&bull; Muscle weakness.</p> <p>&bull; Joint pain.</p> <p>&bull; Depression.</p> <p>&bull; Memory problems.</p> <p>Dry skin is a common symptom of hypothyroidism because thyroid hormones affect the skin&rsquo;s moisture and elasticity.Low thyroid hormone levels can reduce the production of natural oils and cause the skin to become dry, flaky, and itchy.</p>

<p>This is false because cortisol production does not decrease with ageing. Cortisol is the main stress hormone that helps the body adapt to various challenges.In fact, ageing can increase cortisol levels due to chronic inflammation, psychological stress, or impaired feedback regulation.Elevated cortisol levels can have negative effects on glucose control, cardiovascular health, and cognitive function in older adults with diabetes.</p>

<p>This is wrong because aging does not increase blood flow.Blood flow may decrease with age due to various factors, such as atherosclerosis, hypertension, and diabetes.Reduced blood flow may impair wound healing by limiting oxygen and nutrient delivery to the injured tissue.</p>
