Ask a dementia specialist whether repeated requests for food signal hyperphagia — persistent excessive eating — memory loss, blood-sugar trouble, or a medicine effect, and what to track before changing meals. Bring notes on meal timing, portion size, sweet cravings, weight, glucose readings, and new prescriptions. Hyperphagia often starts in the middle stage. A longitudinal study found it affects about 23–51% of people with dementia, with frequent food requests, faster eating, and larger portions, according to the authors of the longitudinal study in Clinical Interventions in Aging.

Why is hunger constant in middle-stage dementia?
Damage to frontal and temporal lobes can impair fullness cues, impulse control, and meal memory. Overeating with sweet or carbohydrate preference and mouth-focused behavior is a core diagnostic feature of behavioral-variant frontotemporal dementia, according to researchers in the 2015 JAMA Neurology study. Ask whether the pattern fits that brain-based drive or another cause.
Describe speed of eating, portion growth, and new fixation on sweets, biscuits, or putting objects in the mouth. Ask what examination or history can separate disinhibition from hunger, anxiety, or boredom. Clear labels guide food access rules and daily routine.
Is forgetting meals causing double meals?
A person may forget eating and ask to eat again. The Royal Free London NHS Foundation Trust leaflet notes this pattern can cause unneeded weight gain and disrupt diabetes control. With diabetes, both missed and repeated meals matter.
The Alzheimer's Society UK explains that forgetting meals can cause low blood sugar, while repeated eating and a new preference for very sweet foods can keep glucose high, as described in Alzheimer's Society UK guidance on dementia and diabetes. Ask to review glucose logs, medication timing, and signs of lows and highs. Ask whether a simpler regimen, supervised meals, or changed monitoring would lower risk.
Could medicines, mood, teeth, or sleep play a role?
Prescribed medicines can shift appetite through nausea, stomach cramps, constipation, sedation, dry mouth, or increased hunger. The East Lancashire Hospitals NHS Trust dietetics leaflet says a sudden rise in appetite warrants review of new drugs, doses, mood, dental pain, and sleep.
Bring a full drug list with start dates and dose changes. Note low mood, restless nights, sore gums, loose dentures, or chewing pain. Ask these checks at the visit:.
- Which drug could raise hunger or dull fullness, and can dose, timing, or choice change?
- Could low mood, poor sleep, or mouth pain drive grazing?
- What weight, appetite, and bowel pattern should trigger a call?
How do we keep eating safe and weight steady?
Middle- and late-stage Alzheimer's commonly brings chewing and swallowing difficulty. The National Institute on Aging notes higher risk of choking, aspiration pneumonia, weight loss, malnutrition, and dehydration, with need for small soft pieces, no straw use, and speech-therapy assessment. Ask for a swallow check if coughing, pocketing food, drooling, chest infections, or fear of choking appear.
Ask which textures, bite sizes, pacing, posture, and supervision fit now. For daily control, the Kent Community Health NHS Foundation Trust leaflet suggests five to six small meals daily, large portions of vegetables or salad, low-calorie snacks such as apples and carrots, sugar-free sweets or gum for sweet preference, and reduced refined sugars with weight tracking, detailed in the Kent Community Health nutrition leaflet on dementia. Ask the specialist to set a target weight range and weigh-in schedule.
