Nursing Home Malnutrition and Dehydration: Signs and Citations

Mild malnutrition may cause no symptoms, so a resident can seem fine even while they're not getting what their body needs. Common clues are feeling tired, feeling dizzy, and losing weight.

During a visit, also watch for:

• Losing weight without trying
• Repeated infections, or wounds that take a long time to heal
• Skin that is dry, or hair and nails that break easily
• Puffy swelling in the legs, feet, or abdomen

Older adults, and people living with lasting health conditions, are more likely to develop it. It often starts with an unbalanced diet, trouble swallowing, dental or digestion problems, or medicines that make food taste or smell different. Trouble digesting food or absorbing nutrients can also lead to it, and missing even a single vitamin can do it.

Seniors, and people with illnesses such as diabetes, face greater dehydration risk. Certain medicines, including water pills, can cause frequent urination and fluid loss. A resident may also drink too little during illness or nausea, or when a sore throat or mouth sores make swallowing hurt.

Mild to moderate dehydration can show up as thirst, a mouth that feels dry or sticky, and urinating less than normal. Other clues are urine that looks darker yellow, skin that feels dry and cool, headache, and muscle cramps.

Severe dehydration can be life-threatening and needs emergency care. One sign is irritability or confusion; others include not urinating, or urine that looks very dark yellow or amber. Without treatment, severe dehydration can bring seizures, permanent brain damage, or death.

MedlinePlus says to call 911 if the person seems less alert than usual, for example confused or having seizures, or runs a fever above 102°F (38.8°C).

The nutrition and hydration rule sits inside the quality of care rules, 42 CFR 483.25, section (g). That edition was issued on October 4, 2016. A home's duties rest on a comprehensive assessment, meaning a complete look at each resident's health and needs.

The rule says the home must:

• Make sure each resident gets enough nutrition to keep an appropriate body weight and the right balance of body salts (electrolytes)
• Offer enough fluids so each resident stays hydrated and healthy
• Offer a therapeutic diet, which is a special eating plan, when the resident has a nutrition problem and their health care provider orders one

This nutrition duty does not apply if the resident's health condition makes it impossible, or if the resident chooses otherwise.

A resident who eats enough alone or with help may only receive a feeding tube when it is medically necessary and the resident agrees. Anyone being tube fed must receive care aimed at helping them return to eating by mouth, if possible.

The home must also guard against problems tied to tube feeding. These problems include dehydration, diarrhea, vomiting, pneumonia caused by food or fluid entering the airway, and open sores in the nasal and throat passages. IV fluids must be given according to professional standards and the physician's instructions.

Inspectors use the code F692 for findings that a home failed to provide enough food or fluids to maintain a resident's health. In the CMS files released October 8, 2026, inspectors cited food and fluid problems under F692 5,099 times at 4,046 homes. These records cover standard inspections and complaint visits across roughly the last three inspection cycles, not a single year.

Certain citations go further and find that residents suffered real harm. The gravest finding is immediate danger, where inspectors believed a resident could be seriously injured or die.

These numbers come from the CMS Care Compare files. Every home's record on this site comes from the same files, which are updated each month. You can look up any home's citations by name, city, or ZIP with the site search, and set two or three homes next to each other with the compare tool.
