Every nutrition & hydration term, acronym, and concept you'll encounter in the caregiving industry — clearly defined.
Reduced interest in eating or drinking that may happen because of illness, depression, medication effects, dementia, or end-of-life decline. Caregivers should encourage fluids and meals gently without forcing food.
Observing how much a client eats or drinks and noticing changes in hunger, swallowing, or meal participation. Appetite changes may be early signs of illness, pain, emotional distress, or decline.
Gentle methods used to encourage eating, such as offering favorite foods, creating calm mealtime settings, or serving smaller meals more often. Positive meal environments may improve nutrition and comfort.
The chance that food, drink, or even spit can go down the wrong way and into the lungs. This is dangerous and more common in people who are weak or near the end of life. Watch for signs like coughing during meals, wet-sounding voice, or trouble swallowing—and report them right away.
Swelling or fullness in the abdomen caused by gas, constipation, digestive problems, or fluid buildup. Severe bloating may affect comfort, appetite, or breathing. Clients may also appear restless or complain of abdominal pressure when bloating worsens.
A lack of important nutrients, vitamins, fluids, or body substances needed for healthy functioning. Deficiencies may cause weakness, fatigue, poor healing, confusion, or physical decline over time.
A condition that occurs when the body does not have enough fluids to function properly. Signs may include dry mouth, dizziness, dark urine, confusion, weakness, or fatigue. Older adults are at higher risk because they may not feel thirsty even when dehydrated.
A gentle cue to help clients follow approved dietary instructions such as low-salt meals, thickened liquids, diabetic-friendly foods, or hydration schedules. Clear reminders support safety without sounding controlling.
The body’s process of breaking down food so nutrients can be absorbed and used for energy and health. Digestive problems may lead to bloating, constipation, nausea, diarrhea, or discomfort after meals.
Support provided during meals to help clients eat comfortably and safely. This may include positioning, pacing, opening containers, or observing for chewing and swallowing difficulties.
A condition where the mouth does not produce enough saliva, causing dryness, discomfort, cracking, swallowing difficulty, or bad breath. Medications, dehydration, and illness commonly contribute to dry mouth in older adults.
Support provided during meals to help clients eat safely, comfortably, and with dignity. Assistance may include opening containers, cutting food, cueing, or monitoring swallowing safety according to the care plan.
Gas buildup in the digestive system that may cause bloating, abdominal pressure, cramping, or discomfort. Changes in diet, digestion, medications, or activity level may increase flatulence in older adults. Persistent or painful digestive discomfort should be observed carefully and reported if unusual or worsening.
Gently reminding and encouraging clients to drink enough fluids throughout the day. Proper hydration may help reduce confusion, dizziness, constipation, and urinary problems.
Understanding approved food textures such as soft, chopped, minced, or pureed diets for clients with swallowing or chewing difficulties. Incorrect food textures may increase choking risk.
Watching for signs of dehydration such as dry mouth, dark urine, dizziness, confusion, or fatigue. Older adults may not always recognize or express thirst clearly.
Gentle verbal prompts or routines used to encourage regular fluid intake throughout the day. Frequent reminders may help clients who forget to drink water independently.
Staying hydrated supports mood, energy, and physical health. You may remind the client to drink water, offer fluids at regular times, or track intake if the care plan requires it. You’re not forcing water—you’re encouraging wellness. Small sips throughout the day can make a big difference.
Gently encouraging clients to eat meals and drink fluids according to their care needs and preferences. Proper nutrition and hydration support healing, energy, and comfort.
Observing how much juice or sugary beverages a client drinks, especially if the client has diabetes or dietary restrictions. Fluid choices may affect hydration, blood sugar, and nutrition.
Awareness of ketones in clients with diabetes, especially during illness or very high blood sugar levels. High ketone levels may signal a serious medical condition called diabetic ketoacidosis. Symptoms such as nausea, confusion, or fruity breath odor should be reported immediately.
Dry, cracked, or peeling lips caused by dehydration, illness, oxygen use, medications, or environmental dryness. Severe dryness may become painful or increase infection risk.
Observing and recording how much fluid a client drinks throughout the day. Low fluid intake may increase the risk of dehydration, constipation, confusion, or urinary problems. Accurate monitoring helps the care team identify health concerns early.
Monitoring diarrhea or unusually loose bowel movements that may increase dehydration, skin irritation, or infection risk. Persistent bowel changes should be reported promptly to the care team.
Noticing reduced interest in meals, smaller food portions, or refusal to eat. Poor appetite may be linked to illness, depression, pain, medication side effects, or swallowing difficulty. Ongoing appetite changes should be reported to the care team.
Awareness of dietary instructions limiting salt intake for clients with heart disease, kidney problems, or high blood pressure. Caregivers should follow meal plans and avoid adding restricted foods outside the care plan.
Increased risk of poor nutrition caused by low appetite, swallowing problems, illness, depression, or difficulty preparing meals. Malnutrition may lead to weakness, weight loss, confusion, or slower healing. Older adults with chronic illness may face higher nutritional risks over time.
Recording how much food and fluid a client consumes during meals throughout the day. Intake tracking helps identify dehydration risk, poor appetite, swallowing difficulty, or nutritional decline.
Proper positioning during meals helps reduce choking risk and supports safer swallowing. Clients are often safest when sitting upright with head and neck properly aligned. Good positioning may also improve comfort and appetite during meals.
Refusing food or drinks during mealtimes because of illness, confusion, depression, swallowing difficulty, pain, or personal preference. Repeated meal refusal may increase dehydration and malnutrition risk.
Monitoring clients during meals to help reduce choking risk, encourage safe swallowing, and ensure proper food intake. Some clients may require close supervision because of cognitive or swallowing difficulties.
Changing the texture of food to make eating and swallowing safer for clients with chewing or swallowing difficulties. Meals may be softened, chopped, minced, or pureed depending on the care plan.
Support provided during meals to help clients eat safely and comfortably. This may include cutting food, opening containers, monitoring swallowing, or encouraging hydration while preserving dignity and independence.
Small amounts of food, liquid, or saliva entering the airway or lungs without obvious choking signs. Repeated microaspiration may increase the risk of pneumonia or respiratory infections. Caregivers should observe for coughing, throat clearing, or wet-sounding breathing after meals. Positioning and slow feeding techniques may help reduce aspiration risk.
Dryness affecting moist body tissues such as the mouth, nose, throat, or eyes. This may occur because of dehydration, oxygen therapy, medications, or illness. Severe dryness may increase discomfort, irritation, or infection risk. Proper hydration and moisture support may help improve comfort levels.
A tube inserted through the nose into the stomach to provide nutrition, fluids, or medication when a person cannot eat safely by mouth. Caregivers may help monitor comfort and tube safety. Any redness, leakage, or breathing difficulty should be reported immediately.
Difficulty absorbing vitamins, minerals, or nutrients properly from food during digestion. Poor absorption may lead to weakness, fatigue, weight loss, or nutritional deficiencies over time.
You don’t make diet plans, but you stay aware of what’s in the care plan—like low sodium, soft foods, or high fiber needs. If a client refuses meals or seems confused about food, you report it. Your job is to respect their preferences and help keep meals safe, enjoyable, and aligned with their needs.
When the body does not receive enough important nutrients like protein, vitamins, or minerals to function properly. Signs may include weakness, weight loss, fatigue, poor healing, or confusion. Older adults are especially vulnerable to nutritional deficiencies during illness or appetite loss.
Physical weakness and reduced body reserves caused by poor nutrition, weight loss, or inadequate food intake over time. Frailty increases the risk of falls, illness, and delayed recovery.
A noticeable decrease in eating or drinking habits over time. Reduced intake may increase the risk of dehydration, weakness, weight loss, and poor healing.
Observing how much a client eats or drinks and watching for appetite changes, weight loss, swallowing difficulty, or meal refusal. Nutrition patterns can reveal important health changes over time. Accurate monitoring helps the care team identify risks early.
Assistance provided to help clients regain strength and nutrition after illness, surgery, infection, or poor appetite. Meal encouragement, hydration, and monitoring may support recovery progress.
A process used to identify clients who may be at risk for malnutrition, dehydration, or unintended weight loss. Early screening helps the care team respond before health complications become severe.
The use of protein drinks, vitamins, meal replacements, or nutritional products to support clients who are not getting enough nutrition from regular meals alone. Supplements may help maintain weight, strength, and healing.
Strong dislike or refusal of food, drinks, medications, or oral care because of pain, nausea, sensory sensitivity, or swallowing difficulty. Oral aversion may affect nutrition and hydration. Gentle approaches and supportive routines may help reduce distress during meals or oral care tasks.
Encouraging safe fluid intake throughout the day to help prevent dehydration, constipation, confusion, and urinary problems. Some clients may need reminders or adaptive cups.
Difficulty swallowing caused by problems in the mouth or throat muscles. Clients may cough during meals, choke easily, or have trouble safely swallowing food or liquids.
Drinking or receiving too much fluid, which may cause swelling, breathing difficulty, confusion, or electrolyte imbalance. Some medical conditions require careful fluid monitoring.
A condition involving compulsive ice chewing, often linked to iron deficiency anemia or nutritional imbalance. Persistent pagophagia should be medically evaluated.
The wave-like muscle movements that move food and waste through the digestive tract. Slow or abnormal peristalsis may contribute to constipation, bloating, or digestive discomfort.
Excessive urination that may occur with diabetes, infection, medication use, or kidney-related conditions. Frequent urination may increase dehydration risk in older adults.
Persistent thirst or inability to feel satisfied after drinking fluids. It may be associated with dehydration, diabetes, medication effects, or certain medical conditions.
Fatty, greasy, or foul-smelling stool caused by improper digestion or absorption of fats. It may be linked to digestive disorders or pancreatic problems.
A state where the body does not have enough fluids, increasing the risk of dizziness, confusion, constipation, or weakness.
Many clients forget to drink water or avoid it to reduce bathroom trips. Your role is to encourage hydration gently—offering water throughout the day, tracking intake (if required), and noticing signs of dehydration. Water is wellness, and you help it happen.
Xylitol is a sugar substitute found in some gums, candies, and oral care products. Caregivers may see it recommended for dry mouth support, but they should follow care instructions carefully and monitor for swallowing concerns or dietary restrictions.
