Abstract

Background: Although abnormal blood pressure is predominantly associated with hypertension, the issue of hypotension remains insufficiently explored. Chronic asymptomatic hypotension, in particular, is rarely addressed in clinical nutrition research. This study aimed to evaluate the impact of targeted dietary modifications on blood pressure as well as selected biochemical, anthropometric, and lifestyle parameters in an individual with low baseline blood pressure. Methods: A single-subject observational study was conducted on a 23-year-old woman with chronic hypotension. Following a 4-week baseline period, a 4-week dietary intervention was implemented involving increased sodium and fluid intake, the introduction of coffee, and overall caloric enhancement combined with increased physical activity. Blood pressure was measured three times daily; anthropometric, biochemical, and lifestyle data were recorded weekly. Results: The intervention resulted in an increase in both systolic (from 93.76 to 101.21 mmHg) and diastolic (from 57.51 to 59.43 mmHg) blood pressure. The subject also reported improved energy levels, longer sleep duration, and reduced daytime fatigue. However, changes in anthropometric parameters were minimal and biochemical outcomes remained inconclusive. Conclusions: The findings suggest that dietary and lifestyle modifications may positively influence blood pressure and subjective wellbeing in individuals with hypotension. There is a clear need for further research focussing on the effects of dietary modifications on blood pressure parameters in individuals with hypotension.
