The importance of Mediterranean diet and hydration habitus in patients with lower limb ulcers: A pilot study

Abstract

Chronic leg ulcers are a common condition among adults, causing pain and social distress. Population aging has contributed to the amplification of the disease with increased cardiovascular diseases such as myocardial infarction, stroke, limb ischemia, cancers, chronic respiratory diseases, and diabetes. The aim of this study was to evaluate the influence of the Mediterranean Diet (MD) and hydration on the healing rate of the ulcers. A group of 35 patients (M/F 16/19, mean age 78 ± 10 years) with venous, arterial, or mixed ulcers was subjected to a Food Frequency Questionnaire (FFQ) and a Hydration Habits Questionnaire (HHQ). Clinical and anthropometric data were collected. A one-year follow-up was conducted. Complete ulcer healing was observed in 26% of the patients, of whom 67% had a habit of high hydration (more than 1 liter /day), regardless of adherence to the MD. In our study population, about half showed a low adherence to the MD. A moderate-high adherence to the MD showed an increase of arterial ulcer healing compared to subjects with a low adherence to the MD, however, only when associated to a consumption of more than 1 liter of water daily. In conclusion, dietary assessments could help identify patients who are likely to benefit from nutritional interventions for improving overall health and wound healing. The habit of high hydration, namely more than 1 liter daily, can influence the wound healing rate.
