Dietitian Case Study: Kelly came for a Dietitian assessment as she was concerned about a large amount of unintentional weight loss she had experienced. Kelly was aged in her sixties, was diagnosed with Parkinson’s in 2016 and was living with her husband.
During assessment, the following information was obtained:
Current weight: 64 kg (141 pounds)
Estimated healthy weight range: 56-69 kg (123-152 pounds)
Kelly reported the following:
- 18 kg (39 pounds) weight loss in a 12-month period. Weight stable previous 2-months.
- Decreased food intake, no hunger, full bloated feeling after eating small amounts.
- Doesn’t always feel like her levodopa kicks in.
- No chewing or swallowing issues.
- Takes levodopa-containing medication at 6am, 10am, 2pm, 6pm.
- Mealtimes approximately: breakfast 6am, lunch 1pm, dinner 6pm.
- No snacks consumed in-between meals.
Issues:
- Significant weight loss. Weight now stable. Loss of muscle mass and likely strength.
- Inadequate food intake and not meeting nutritional requirements.
- Possible gastroparesis or slow stomach emptying (based on reported symptoms).
- Potential food and levodopa interactions.
Dietitian notes:
- Weight loss is commonly observed in people with Parkinson’s. Early detection of weight loss and malnutrition is critical.
- Protein can interfere with how well levodopa is absorbed.
- With slow stomach emptying food can remain in the stomach for an abnormally long time and any levodopa taken while the stomach is full of food will be unable to exit into the small intestine. Instead, the levodopa must wait until the stomach clears.
Dietitian case study – Treatment goals:
- Optimise nutritional intake
- Prevent further loss of weight
- Assist to increase muscle mass (ensure adequate protein intake)
- Minimise potential food and levodopa interactions
Suggestions made following assessment:
- Take levodopa on an empty stomach i.e. 30 minutes before a meal.
- Change mealtimes to minimise potential food and levodopa interactions.
