5'6 ft tall, and weigh 235 lbs - Will I be a good candidate for the Gastric Balloon?

You can be a good candidate for gastric balloon but it really depends on your detailed medical history . Weight loss can be helpful in lowering your blood pressure. Presently there are other non invasive options available where you don’t need to cut stomach in half. One of non invasive procedures is endoscopic sleeve Gastroplasty. Please speak with board certified physician to discuss options available to you.

I think that the gastric balloon can help you lose some weight, the disadvantage that I see is that when you remove it the stomach will be bigger and thicker, which will favor more food to enter and recover the little weight lost, I am in favor of gastric sleeve surgery that has better results in the long term

Thank you for sharing your information. Based on your height and weight, your Body Mass Index (BMI) is calculated at 37.9. This places you in the category of Class III Obesity, which is classified as "severe" obesity and is associated with a higher risk of various health issues related to excess weight, including high blood pressure.
I understand your concerns about not wanting a surgical procedure that involves cutting the stomach. It's important to note that there are different options available for weight loss, and each has its advantages and considerations. The gastric balloon is a temporary, non-surgical weight loss option that can assist with approximately 35 pounds of weight loss. However, it's essential to understand that the results from the gastric balloon are typically more modest compared to surgical options.
On the other hand, the gastric sleeve surgery involves the removal of approximately 70% of the stomach, creating a smaller stomach pouch. This results in reduced calorie intake and a sensation of fullness more quickly, which can lead to more significant and sustained weight loss. Many patients who undergo the gastric sleeve experience life-changing improvements in both their physical health and emotional well-being.
Given your current BMI and concerns, I would lean towards recommending the gastric sleeve as it tends to provide more substantial and longer-lasting weight loss results, which can better address your severe obesity and associated health issues. However, it's crucial to have a comprehensive evaluation and consultation with a bariatric surgeon who specializes in both the gastric balloon and the gastric sleeve. They can assess your individual medical history and specific needs to guide you in making the most appropriate decision for your weight loss journey. Weight loss surgery is a significant decision, and having the support and expertise of a bariatric surgeon is invaluable in helping you achieve your goals and improve your overall health.
