Mark Harmon, known for his role as Navy Special Agent Jethro Gibbs on NCIS, is reportedly facing health concerns, leading friends to worry about his well-being. The 65-year-old actor, once a sturdy 6-foot-1 college football star, has allegedly lost over 20 pounds, dropping to 157. He has become reclusive and rarely leaves his home, presenting a stark contrast to his former athletic self.

A source close to the actor expresses concern, stating, “Mark appears to have wasted away” and notes his diminished energy levels. Friends, accustomed to his active lifestyle, are deeply worried about the change.

Despite Mark’s representative denying any health issues, insiders suggest that Mark may be haunted by his father’s sudden passing due to a heart attack. His father, Tom Harmon, a renowned college football star, suffered the same fate. Dr. Stuart Fischer, an internist, emphasizes the importance of monitoring heart health, particularly in individuals with a family history of heart disease.

The recent passing of NCIS creator Gary Glasberg has further impacted Mark, prompting him to consider retirement after the upcoming 15th season. Fans are urging him to prioritize his health and well-being before it’s too late.

Overall, Mark Harmon’s health and well-being have become a subject of concern among those close to him, who hope he will take the necessary steps to prioritize his health and longevity.
