Weight loss surgeries like bariatric surgery can be life-changing. The decision to proceed with this surgery must only be taken when all other attempts to reduce weight through weight loss programs, dieting and exercise have been exhausted.
Bariatric Surgery Candidates
Bariatric surgery is done for patients who are overweight and obese with or without health related risks. Usually patients consisting of a BMI of 30 or more can be considered for the surgery. By withstanding the surgery, health conditions may improve; such as any weight related medical diagnosis such as heart disease, hypertension, type 2 diabetes, and sleep apnea.
This surgery is irreversible and expensive, therefore it is not for everyone. To qualify, you need to meet certain medical guidelines and go through an extensive screening process.
95% of all people who have had this surgery said that their quality of life has improved (1). Research has shown that on average people have lost 90 pounds, following the gastric sleeve procedure(2). However, your physician is the best person who can advise the right techniques of bariatric surgery suitable for individuals.
How Bariatric Surgery Influences Weight Loss
This surgery makes your stomach pouch one-quarter of its original size, in doing so, limitations will be placed on the volume of consumption. Eating a reduced amount of food, along with the overall absorption from calories decreasing, may result in rapid weight loss.
Additionally bariatric surgery reduces the body’s ability to produce the hunger hormone, ghrelin. Furthermore producing the ability to lose weight.
The most rapid weight loss will be achieved within the first 12 months post-operatively. Patients can take advantage of this statistic by following the post-operative diet guidelines. The post-operative diet includes information about healing and recovery; including what foods to consume, the proper amounts, and what to avoid. The details allow patients to return to health while optimally caring for their new stomach.
Once your stomach is healed, you can start consuming regular textured foods, together with solid foods.
During the span of recovery, you may experience certain symptoms and some physical discomfort.
Symptoms you may experience over 6 months after surgery:
- Body Aches
- Tired and Fatigue
- Dry Skin
- Mood Changes
- Hair Shedding or Thinning Hair
- Acid Reflux
- Dumping Syndrome
These symptoms are normal as you have lost major weight and your body is reacting to the change after surgery. As your healing continues, these reactions will subside.
Post-Operative Diet Outlined
Initially after surgery, liquids will be the only thing manageable. Followed by Protein based liquids, and pureed foods. Thereafter depending upon tolerant levels of foods and the recovery process of the body, transitioning into the next phases can vary. Some patients may progress faster or slower than others depending on their healing abilities.
Listening and following through with the body’s cues, like physical hunger, is a key component for life after bariatric surgery. Introducing a wider variety of foods with different textures and consistency, can be challenging. Once the body is ready to move into the next phase, patients can start to enjoy soft foods followed by regular textured foods.
