Here's some helpful information about boosting appetite in elderly sick individuals:

• Understanding Appetite Loss in the Elderly
  Appetite reduction in elderly people can be caused by various factors such as chronic illnesses, medications, depression, dental problems, or changes in taste and smell.

• Medical Evaluation
  It’s important to consult a doctor to identify any underlying causes before starting any treatment for appetite loss.

• Appetite Stimulant Medications
  Some medicines like Megestrol acetate and Mirtazapine are sometimes used to stimulate appetite. These should only be taken under medical supervision due to potential side effects and interactions.

• Nutritional Supplements
  Supplements such as zinc, vitamin B complex, and omega-3 fatty acids may help support appetite and overall nutrition.

• Non-Medication Approaches
  Practical steps include offering small, frequent meals, enhancing food flavor, and addressing any dental or swallowing difficulties to make eating easier and more enjoyable.

• Monitoring and Follow-up
  Regular follow-up with a doctor is essential to monitor progress and adjust treatment as needed.

• When to Seek Specialist Care
  If appetite loss persists or worsens, consulting specialists like geriatricians or dietitians can provide more tailored care.

Please consult a doctor or a geriatric specialist to discuss the best and safest options for appetite improvement based on the specific health condition.
