Although we encourage most kids to be active and play sports as part of a healthy lifestyle and to avoid childhood obesity, there are some sports that children with certain medical conditions should avoid. These medical conditions include children who have atlantoaxial instability (Down syndrome), bleeding disorders, hypertension, congenital heart disease, an enlarged spleen, poorly controlled seizures, etc.

Restrictions on Contact Sports

In most cases, if a child has to avoid playing sports, it is only contact sports that they have to avoid. And while most parents can easily recognize sports like football and hockey as contact sports, some others are more surprising.

If your child is not supposed to play contact sports or collision sports, then he should likely avoid:

Basketball
Boxing
Diving
Field Hockey
Tackle Football
Ice Hockey
Lacrosse
Martial Arts
Rodeo
Rugby
Ski Jumping
Soccer
Team Handball
Water Polo
Wrestling

In some circumstances, you may also need to avoid other limited contact sports, such as:

Baseball
Bicycling
Cheerleading
White Water Canoeing or Kayaking
Fencing
Field Events, Such as High Jump and Pole Vault
Floor Hockey
Flag Football
Gymnastics
Handball
Horseback Riding
Racquetball
Ice Skating
In-Line Roller Skating
Downhill Skiing
Cross-Country Skiing
Water Skiing
Skateboarding
Snowboarding
Softball
Squash
Ultimate Frisbee
Volleyball
Windsurfing
Surfing

One Kidney Sports Restrictions

If a child is born with a single or solitary kidney or if he has one kidney removed, then he will likely need to take steps to avoid injuring the remaining kidney. And this usually means avoiding contact sports, especially heavy contact sports.

Although the National Kidney Foundation states that the limitation might also include heavy contact or collision sports, including "boxing, field hockey, football, ice hockey, lacrosse, martial arts, rodeo, soccer and wrestling," the American Academy of Pediatrics states that children with a solitary kidney need "individual assessment for contact, collision, and limited-contact sports" before they participate.

Keep in mind that the risk of injury to a solitary kidney can depend on whether the kidney is healthy, enlarged, out of position, etc. and that children are sometimes allowed to play contact sports if everyone understands the risks, especially if the child wears protective pads and the sport can be modified to be safer for the child.

Mono Sports Restrictions

Children with mono and an enlarged spleen, which can rupture, are supposed to "avoid all sports" according to the AAP.

Sports Restrictions and Other Medical Conditions

There are many other medical conditions that can limit a child's participation in sports. However, there are few one size fits all rules and so you might talk with a specialist about whether or not your child with a medical problem can play a certain sport. The AAP states that the level of competition, availability of protective equipment if the sport can be modified, etc., can all help determine if a child can play.

Some other chronic medical conditions that may limit (or modify) a child's participation in sports can include:

Atlantoaxial instability
Bleeding disorder, such as hemophilia
Cardiovascular disease, including high blood pressure, congenital heart disease, irregular heart rhythms, and non-innocent heart murmurs
Cerebral palsy
Diabetes mellitus
Functionally one-eyed athletes
Enlarged Liver
Malignant neoplasm (cancer)
Musculoskeletal disorders
Neurologic disorders, including a history of head trauma, spine trauma, or poorly controlled seizures
Obesity
Organ transplant recipient
Respiratory conditions, such as cystic fibrosis and asthma
Sickle cell disease
Sickle cell trait
Undescended or Absent Testicle (the child may need to wear a protective cup)
