There’s a common misconception that Scuba Diving is an extreme watersport that requires divers to have peak levels of body fitness and stellar physique. But in reality, scuba diving is one of the most diverse and inclusive activities in terms of age, body weight, and even physical disabilities.
As long as you’re healthy and have a basic level of fitness, there’s nothing standing in your way to take the dive. During my years of diving, I’ve come across numerous plus-sized divers as well as Diving Instructors who are more skilled and adept at this sport than I ever will be.
To be precise, there’s no officially mandated bodyweight limit for a person to be able to learn and enjoy scuba diving. As long you’re physically healthy with no underlying medical conditions there should be no difficulty in getting your Diving certification.
That being said, however, being overweight can have passive implications related to health and mobility which might impact your diving experience. At a time, when obesity is becoming a mainstream problem in many first-world countries including the USA we must always try to keep our weight in check and strive to become healthier regardless.
In this article, I will try to jot down everything you need to know to get started with scuba diving as an overweight person. I will also try to explain all the potential roadblocks you may face in your diving journey due to weight issues.

Is It Safe for Overweight People to Scuba Dive?
As mentioned earlier, it is perfectly okay for overweight people to go scuba diving as long as they don’t have any underlying health conditions. However, complications may arise if you’re clinically obese and have health problems as a direct result of obesity such as coronary heart disease, cholesterol, or high blood pressure.
Most training institutions require you to submit medical approval certificate beforehand if you have any health implications. For example, the PADI open water certification course requires you to fill out a medical form waiver stating your proficiency level in swimming and indicate your medical conditions if you have any, honestly. It is advisable to fill out the questionnaire form honestly for your own safety as well as your dive instructor and fellow divers in the future.
It’s worth noting that not disclosing your health conditions honestly may lead to your diving health insurance provider forfeiting your insurance coverage in case you suffer a diving-related accident.
What Are the Implications of Scuba Diving as An Overweight Person?
Being overweight doesn’t necessarily mean you cannot enjoy wandering in water depths. What matters the most is that you have basic levels of fitness. It’s better to be overweight and fit than to be skinny with low body fitness. That being said, some complications may arise as a direct result of your weight profile and you must keep these possible scenarios in mind. Exercising a little caution will help you avoid most of these problems.
Increased Risk of Medical Issues
Being overweight is associated with the risk of several health conditions, such as high blood pressure, diabetes, breathing problems, and heart disease. If you suffer from any of these medical conditions, you should consult with a healthcare professional (preferably a diving doctor) before diving to assess the risk and determine whether you can safely dive.
Scuba diving is a physically demanding activity that requires a certain level of physical fitness. You may find it more difficult to cope with the physical demands of diving, such as carrying heavy diving gear, swimming against currents, and maintaining a horizontal streamlined position underwater. This can result in a higher risk of injury, exhaustion, and fatigue.
Being obese basically means you’re carrying extra weight on you which leads to greater energy consumption than people with lighter weight. So in water, you are prone to using more oxygen than divers with lower weight and risk running out of breathable air quicker.
Add to that the weight of the scuba equipment you’re carrying it can become challenging to maneuver swiftly underwater and control buoyancy. This may also result in the need for more weight to be added to your diving gear, making it even more difficult to move around.
Increased risks of decompression sickness (DCS)
Decompression sickness (DCS), also known as “the bends,” is a potentially life-threatening condition that can occur during or after scuba diving. It happens when nitrogen bubbles form in the bloodstream and tissues due to a rapid decrease in pressure during ascent. The symptoms of the bends can range from mild joint pain and skin rashes to more severe neurological symptoms, such as dizziness, confusion, and paralysis.
While DCS can happen to anyone, being overweight puts you at a higher risk due to several factors related to your physiology and health status.
One of the primary factors that increase the risk of DCS if you’re overweight is the increased amount of adipose tissue (fat) in your body. Adipose tissue has a higher blood flow than muscle tissue, which means that it absorbs nitrogen more readily. If too much nitrogen is absorbed into the body tissues, it can form bubbles that can rapidly trigger DCS.
Another factor that contributes to the increased risk of DCS for overweight individuals is reduced physical fitness. Overweight individuals in general often have a lower level of cardiovascular fitness, which can make them more susceptible to the effects of DCS.
Limitations in Equipment Size
As an overweight individual, finding properly fitting equipment is a pain. Standard scuba diving equipment is generally designed, keeping in mind the standard body size and weight. Fortunately, many scuba diving manufacturers now offer a range of accommodative equipment, such as wetsuits, fins, and buoyancy compensators, that are designed specifically for bulkier body types.
I would suggest that if you’re overweight you should invest in gear that fits you as quickly as you can. Because most rentals don’t have a big variety when it comes to different shapes and sizes of diving gear, especially wetsuits, and BCDs.
Properly fitting wetsuits and a well-adjusted BCD that can offset your body weight are essential. Another gear piece that’s often overlooked but is equally essential is the weight belts. You will need to put on more lead on your weight belt than usual to sink which can be strenuous on your back in the long run. It’s better to look for weight harnesses that have a better uniform weight distribution around the shoulders.
Enough About Implications, What About the Positives of Being Bulky While Scuba Diving?
No need to be disheartened now. There are some unusual advantages that are sometimes associated with being slightly overweight while scuba diving.
1. You’re Naturally More Buoyant than The Rest:
People who are slightly overweight tend to have more natural buoyancy in the water, making it easier to maintain neutral buoyancy while diving.
2. Your Body Has Better Insulation:
Extra body fat offers extra insulation in cold water, helping to keep you warmer. Say goodbye to those uncomfy 9mm wetsuits during your cold water dives!
3. Your Dive Buddy Can Spot You More Quicker:
Being overweight makes you more visible underwater due to a larger body size and you’ll be easier to spot by your dive buddy in case of an emergency.
4. You Are in Better Control of Your Breathing:
Extra body fat provides more surface area for the diaphragm, which may help with breathing control while diving.
5. Greater Balance and Coordination Underwater
Yeah, you heard it right. The same weight that is your biggest enemy in maintaining a proper balance on land actually makes you maintain balance with ease underwater. If you’re slightly overweight you have a lower center of gravity, which can provide better balance and coordination while diving.
Safety Tips: How To Exercise Caution While Scuba Diving if You’re Overweight?
Just make sure to pay heed to safe driving practices, and be aware of your surroundings at all times and you’re good to go. I have compiled a list of basic safety tips you should ensure especially if you’re overweight.
- Do regular medical checkups: Health isn’t constant. Keep in touch with a diving doctor and get periodic health checkups.
- Choose the right equipment: Make sure you have the right scuba diving equipment that fits properly, including a wetsuit, buoyancy compensator, and weight system. A well-fitting wetsuit will provide the right amount of insulation without being too bulky or restrictive, while a properly adjusted buoyancy compensator will help you maintain neutral buoyancy underwater.
- Plan your dive beforehand: Plan your dive on land and stay within the safe limits of diving depth. While underwater always be attentive to your dive watch readings. Avoid deep dives or dives in strong currents until you have more experience and have built up your strength and endurance.
- Choose less extreme dive sites: Try to avoid the advanced dive sites and stick with the less extreme ones until you’re habituated to the diving activity and feel confident in yourself.
- Watch your air consumption: You are likely to use more air per unit bodyweight than other divers, so it’s important to keep an eye on your air consumption and plan your dive accordingly.
- Dive with a buddy: Always dive with a buddy and stay close to each other during the dive. This will help you stay safe and provide extra assistance if needed.
- Stay hydrated: Drinking plenty of water before and after diving can help you stay hydrated and reduce the risk of decompression sickness.
- Listen to your body: If you feel tired or uncomfortable while diving, stop your session. Pushing yourself beyond your limits can be detrimental.
Don’t let your weight discourage you from feeling the thrill of scuba diving. Overweight individuals can enjoy the beauty of the underwater world while minimizing the challenges and risks associated with scuba diving.
With the availability of specialized equipment, safe driving practices, and the support of a qualified instructor, you too can experience the thrill and adventure of scuba diving, regardless of your body type or size.
