Assess for clinical signs and symptoms of dehydration, including thirst, weight loss, dry mucous membranes, sunken-appearing eyes, decreased skin turgor, increased capillary refill time, hypotension and postural hypotension, tachycardia, weak and thready peripheral pulses, flat neck veins when the patient is in the
Dehydration is common in older people, leading to longer hospital stays and increased disability and mortality. Health professionals can diagnose water-loss dehydration by taking a blood sample and measuring serum osmolality, but a less-invasive test would be useful.
Top Signs of Dehydration in Seniors
Skin turgor (elasticity) has been mentioned by few studies, but most report its limitations when assessing hydration status in the elderly. The turgor is usually assessed by pulling the skin and observing how long it takes to return to the baseline state; with values longer than 2 seconds associated with dehydration.
Hydration assessment comprised 7 physical signs of dehydration [tachycardia (>100 bpm), low systolic blood pressure (<100 mm Hg), dry mucous membrane, dry axilla, poor skin turgor, sunken eyes, and long capillary refill time (>2 seconds)], urine color, urine specific gravity, saliva flow rate, and saliva osmolality.
10 Symptoms of Dehydration
Symptoms of dehydration in adults and children include:
Summary: Thirst is the body’s first indicator of dehydration. For most people, responding to thirst effectively prevents dehydration. Your urine can tell you a lot about your hydration status, since it accounts for the majority of the fluid that leaves your body.
Most doctors divide dehydration into three stages: 1) mild, 2) moderate and 3) severe. Mild and often even moderate dehydration can be reversed or put back in balance by oral intake of fluids that contain electrolytes (or salts) that are lost during activity.
Changes in body weight, haematological and urine parameters, bioelectrical impedance, skinfold thickness, heart rate and blood pressure changes are among these indices. Plasma osmolality, urine osmolality and urine specific gravity are the most widely used markers of hydration.
