What is Messi’s disease called?

Messi was diagnosed with growth hormone deficiency (GHD) at age 11 after doctors noticed his growth had stalled. This condition means the pituitary gland does not produce enough growth hormone, leading to stunted height if left untreated (Merck Group (pharmaceutical manufacturer)).

What is growth hormone deficiency?

• GHD is a medical condition where the body produces insufficient human growth hormone (Merck Group)
• Untreated, it results in permanent short stature — one estimate says Messi might have reached only about 4 feet 7 inches without intervention (Dartmouth Journeys)
• It is not a performance-enhancing treatment; it’s a medical therapy (Your Health Magazine (health explainer))

How was Messi’s condition treated?

Messi began daily injections of synthetic human growth hormone (somatotropin) around age 11 (Dartmouth Journeys). The therapy cost roughly $900 per month, which his family could not afford on their own (Bleacher Report (sports journalism)). FC Barcelona reportedly agreed to cover the costs as part of the deal that brought him to the club (Bleacher Report).

Did his condition affect his football career?

Without treatment, Messi would have been severely undersized for professional football. The therapy allowed him to reach his current height of 5 ft 7 in (Bleacher Report). The implication: Messi’s growth hormone deficiency was a medical barrier that required expensive treatment. For the player, it became a stepping stone; for the club, a calculated investment that paid off beyond measure.

What happened to Messi at age 13?

At 13, Messi’s life turned when his family moved from Rosario, Argentina to Barcelona. The move was driven by the opportunity to receive growth hormone treatment and join FC Barcelona’s famed La Masia academy (Sports Illustrated (sports journalism)).

Why did Messi move to Barcelona?

• Barcelona’s sporting director Carles Rexach, impressed by Messi’s talent, famously signed him on a napkin after seeing him play (Sports Illustrated)
• The club agreed to cover his hormone treatment costs, which his family could not afford (Bleacher Report)
• His father, Jorge Messi, moved with him while his mother stayed in Argentina with his siblings (Britannica: Lionel Messi)

How did his family support his career?

The Messi family sacrificed financially — his father worked multiple jobs to support the move (The Guardian (news outlet)). The family’s commitment was essential in allowing Messi to pursue his dream.

What was his early career in La Masia?

Messi quickly progressed through the youth ranks, debuting for Barcelona’s first team at 17. At that age, he had 1 goal in 9 La Liga appearances (Transfermarkt (football statistics)). Compare that to Lamine Yamal, who at 17 already had higher goal involvement for Barcelona (ESPN).

Who is best, Ronaldo or Messi?

Five key metrics separate the two titans, and the answer depends on what you value: consistency, peak performance, or trophy haul.

Messi leads in Ballon d’Ors and has a World Cup win — a major legacy anchor. Ronaldo leads in career goals and wealth. The pattern: the GOAT debate remains subjective, but the data tilts differently per category (BBC Sport).

Who was better at 17: Yamal or Messi?

At 17, Lamine Yamal has already produced higher goal involvement in La Liga than Messi did at the same age (ESPN (sports journalism)). However, Messi’s later career overshadowed any slow start.

Will Messi play the 2026 World Cup?

Messi has not publicly committed to the 2026 World Cup, but he has given hints. In a 2024 interview with FOX Sports, he said: “I will keep playing until I can’t anymore.” (FOX Sports (sports broadcaster)). At 39 in 2026, his participation remains uncertain.

What has Messi said about his future?

• “My dream is to play, but the body decides” – Messi, 2024 (ESPN)
• He has not ruled out playing; no retirement announcement as of 2025
• His decision likely depends on health and Argentina’s need for him (BBC Sport)

What is his current form?

At Inter Miami, Messi continues to perform at a high level, leading the team to a Leagues Cup title in 2023 (MLS Soccer). His statistics in MLS remain elite, suggesting he retains the ability to compete internationally.

Is Lionel Messi a billionaire?

Messi’s career earnings have exceeded $1 billion according to Forbes, though his net worth is estimated around $600 million (Forbes (business magazine)). He became a billionaire in career earnings after signing with Inter Miami and the Apple TV deal.

What is Messi’s net worth?

• Forbes estimated $600 million net worth as of 2025 (Forbes)
• Ronaldo is richer, with net worth over $900 million (Forbes)
• Major income sources: MLS salary + Apple TV revenue sharing, Adidas endorsement, Pepsi, and other sponsors (Spotrac (sports salary database))

How does Messi’s wealth compare to Ronaldo?

Ronaldo’s off-field empire — including his CR7 brand, hotels, and social media monetization — pushes his net worth higher. Messi’s wealth is more traditional: salary and endorsements (Forbes).
