From Deanne Winslett, Overdrive:
If you’ve been putting on weight recently and have noticed blurry vision, fatigue or tingling in your hands or feet, don’t ignore those symptoms. They’re likely indicators of poor circulation.
Because of the largely sedentary nature of long-haul driving, truckers have a higher incidence of weak circulation and other heart issues, as well as the interrelated conditions of obesity and diabetes. Recognizing these symptoms early and discussing them with your doctor can help prevent them from worsening.
