Family caregivers' experiences in nutritional management of cancer-diabetes comorbidity: A descriptive phenomenological study

This study aims to explore the experiences of caregivers in providing nutritional management for cancer patients with comorbid diabetes.

We conducted semi-structured interviews with 25 caregivers of patients diagnosed with both cancer and diabetes. The interviews were audio-recorded, transcribed verbatim, and subjected to immersive reading and Colaizzi's analysis, with pseudonyms used to maintain confidentiality.

We identified four key themes that describe caregivers' attitudes and experiences related to nutritional management for cancer patients with comorbid diabetes. The identified themes include (i) Willingly Providing Nutritional Care; (ii) Heavy Physical and Emotional Strain; (iii) Contradictory Dietary Care; (iv) The Pressing Need for Dietary Guidance.

This study shows that family caregivers of patients with cancer and comorbid diabetes place great importance on nutritional issues and demonstrate a strong sense of responsibility and dedication. It also highlights the multifaceted challenges family caregivers face in managing the nutrition of cancer patients with diabetes, including emotional stress, conflicting dietary needs, and limited access to professional guidance. Caregivers urgently require tailored, ongoing dietary support. Establishing a multidisciplinary support system, developing practical educational tools, and leveraging mobile health platforms may effectively reduce caregiver burden and improve comorbidity dietary management.
