Obesity may significantly impact the recovery and discharge outcomes of ischemic stroke patients, according to a recent study conducted in Los Angeles. Ischemic stroke occurs when blood flow to the brain is reduced or blocked, leading to oxygen deprivation in brain tissue. While obesity is already recognized as a major risk factor for such strokes, new findings suggest it might also affect the patient's ability to return home directly after hospitalization.
Researchers at UCLA Medical Center analyzed data from 451 patients admitted for ischemic stroke between 2003 and 2006. The average age of the participants was 65, with 28% being male. Patients were categorized based on their body mass index (BMI) into four groups: underweight (BMI ≤ 25), overweight (BMI 25–29), mild obesity (BMI 30–34), and moderate to severe obesity (BMI ≥ 35). The study found that while the length of hospital stay was similar across most groups, patients with higher BMI were less likely to be discharged directly home. Instead, they were more often sent to rehabilitation centers, nursing facilities, or other medical institutions for continued care.
The results showed that only 26% of patients in the higher BMI group returned home directly, compared to 45% in the lower BMI group. Although there was no significant difference in in-hospital mortality among the groups, the researchers emphasized that obese patients faced greater challenges in achieving independent recovery after discharge. These findings highlight the importance of considering BMI when planning post-stroke care and suggest that weight management could play a role in improving long-term outcomes.
