Morbid Obesity: What is it?

Reading time -

When we talk about weight, it's easy to get lost in numbers. After all, we measure it, we track it, and for many, we let it define our health. But, here's the twist: health isn't merely about the digits on a scale. Yes, weight matters, but it's merely one slice of the health pie. For some, understanding where their weight stands can be a wake-up call about potential health concerns.

Enter morbid obesity. You might have heard the term, but what does it entail? Buckle up as we delve deep into the what, why, and how of morbid obesity. It's time to see the bigger picture—no pun intended.

What is Morbid Obesity?

Let's set the record straight: obesity isn't merely about being "overweight". It's about having an excessive amount of body fat that can potentially be detrimental to one's health. To get technical, healthcare professionals often rely on a tool known as the Body Mass Index (BMI) to gauge obesity. This index is derived from an individual's weight and height. However, it's essential to note that BMI isn't the be-all and end-all. It doesn't account for factors such as muscle mass, bone density, and other critical components. While it offers a decent starting point, it's just that—a starting point.

To paint a clearer picture, BMI categories look somewhat like this:

●      Underweight: BMI below 18.5

●      Normal: BMI of 18.5 to 24.9

●      Overweight: BMI of 25 to 29.9

●      Obese: BMI of 30 and above

Now, what happens when someone surpasses the "obese" threshold? We venture into the realm of morbid obesity. Broadly, there are three classes of obesity:

  1. Class 1: BMI ranges from 30 to 34.9
  2. Class 2: BMI falls between 35 to 39.9
  3. Class 3: BMI of 40 or more

It's that Class 3 category that's synonymous with morbid obesity. It's a territory where the risks amplify, and the implications for one's health become more pronounced.

While it's tempting to oversimplify and attribute morbid obesity to merely overeating, it's vital to understand that the equation isn't just about calories in versus calories out. A myriad of factors, from genetics to lifestyle choices, play a role. So, as we proceed, let's remember to approach the subject with empathy and understanding, recognizing that every individual's journey with weight is uniquely theirs.

Risk Factors for Morbid Obesity

The genesis of morbid obesity is multifaceted, influenced by a concoction of genetic, environmental, and behavioural factors. While the caloric equation (calories in versus calories out) might seem straightforward, our bodies are complex, and the determinants of weight are manifold. Here's a deeper dive into the major risk factors:

1. Family History and Genetics

Can we really blame our genes? To an extent, yes. Genetics do play a part. Individuals with family members who are morbidly obese are more likely to face the same challenge. For instance, research indicates that children with both parents being overweight or obese have a higher predisposition to obesity compared to those with one or no obese parents.

2. Lifestyle Choices

Our day-to-day choices are paramount. Sedentary lifestyles, coupled with diets rich in processed foods, sugars, and unhealthy fats, pave the way to weight gain. The modern world, with its convenience-driven ethos, often fosters these unhealthy habits. Not engaging in regular physical activity exacerbates the issue. The general recommendation? At least 150 minutes of moderate-intensity exercise weekly. But remember, even small increments of movement are beneficial!

3. Age

While morbid obesity can affect individuals at any age, getting older often brings along with it hormonal changes and a slowing metabolism, not to mention decreased physical activity levels. This cocktail of factors makes it easier to gain weight and tougher to shed it.

4. Medical Conditions

Certain medical issues can either cause weight gain directly or make it difficult for individuals to maintain an active lifestyle. For example, conditions such as hypothyroidism or polycystic ovarian syndrome (PCOS) can significantly impact metabolism and, subsequently, weight.

5. Medications

Weight gain is a side effect of several medications. From certain antidepressants to specific diabetes meds, several drugs can potentially contribute to added pounds. It's always essential to discuss potential side effects with your healthcare provider and weigh the pros and cons of any medication.

Signs and Symptoms of Morbid Obesity

It's not always just about the weight. Yes, a significantly high BMI is a diagnostic indicator, but other signs and symptoms include:

●      Difficulty or struggle with day-to-day activities.

●      Becoming winded or breathless quickly.

●      Increased strain on joints and muscles.

●      Accumulation of excessive fat, especially in the abdominal area, as a visible physical indicator.

Remember: diagnosis should always be left to healthcare professionals, considering all the symptoms of morbid obesity.

Diagnosis and Health Risks of Morbid Obesity

A diagnosis of morbid obesity generally revolves around BMI (Body Mass Index), which is a measure derived from an individual’s weight and height. Here's a breakdown:

●      Normal weight: BMI of 18.5 to 24.9

●      Overweight: BMI of 25 to 29.9

●      Obesity: BMI of 30 or higher

●      Morbid obesity: Typically defined as a BMI of 40 or higher or being 100 pounds over ideal body weight.. Another factor that might classify someone as morbidly obese is having a BMI of 35 or higher and experiencing obesity-related health complications.

Clinical evaluations, including physical examinations and a review of medical history, can provide insights into the genesis of obesity in an individual. Tests such as blood pressure measurements, cholesterol and blood sugar levels, liver function tests, and others might be used to gauge the severity and impact of obesity.

Associated Health Risks:

Morbid obesity is not just about weight; it can act as a catalyst for a myriad of health complications:

  1. Cardiovascular Diseases: This includes conditions like coronary artery disease and stroke. Excessive fat, especially visceral fat surrounding internal organs, plays a significant role in cardiovascular risks.
  2. Type 2 Diabetes: Morbid obesity can lead to insulin resistance, the primary precursor to type 2 diabetes.
  3. Sleep Apnea: Excess weight, especially around the neck, can constrict airways, leading to interrupted sleep and other associated issues.
  4. Osteoarthritis: The added weight can strain the skeletal system, leading to conditions such as osteoarthritis, primarily impacting the knees, hips, and back.
  5. Liver Disease: Non-alcoholic fatty liver disease (NAFLD) and it's more severe form, non-alcoholic steatohepatitis (NASH), can be spurred by obesity.
  6. Certain Cancers: Obesity can increase the risk of several types of cancer, including endometrial, breast, colon, and pancreatic.
  7. Gallbladder Disease: Rapid weight gain or loss can induce gallstones, more common in the obese population.
  8. Psychological Effects: Depression, anxiety, and other mental health issues can often be intertwined with morbid obesity. The social stigma attached to weight can also play a role in these psychological challenges.

Treatment Options for Morbid Obesity

The treatment of morbid obesity involves multi-faceted approaches, prioritizing a holistic strategy that melds medical, surgical, and lifestyle-based interventions. Here's a comprehensive look:

1. Lifestyle Modifications:

●      Dietary Changes: Adopting a balanced and nutritious diet is fundamental. Consulting with a registered dietitian can help individuals establish personalized, sustainable dietary plans. Key strategies often include reducing calorie intake, minimizing processed foods, and emphasizing whole, nutrient-rich foods.

●      Physical Activity: Regular physical activity helps burn calories and improve cardiovascular health. A regimen that includes both aerobic exercises, like walking or swimming, and strength training is generally recommended. It's essential to start slowly, especially if one hasn't been active, and gradually increase intensity and duration.

●      Behavioral Counseling: Behavioral therapy helps address emotional and psychological challenges related to food. It can teach coping strategies, stress management, and help break unhealthy eating patterns.

2. Medications:

In some cases, weight-loss medications might be prescribed to complement lifestyle changes. Such drugs can suppress appetite, reduce absorption of dietary fat, or increase feelings of fullness. However, they come with potential side effects, and their long-term efficacy is still under scrutiny. Regular consultations with healthcare providers are crucial when using these medications.

3. Surgical Interventions:

●      Bariatric Surgery: For those who haven't had success with other methods and have serious health concerns due to their weight, bariatric surgery might be an option. Types of bariatric surgery include:

○      Roux-en-Y Gastric Bypass: Reduces the size of the stomach and bypasses a segment of the small intestine.

○      Sleeve Gastrectomy: Removes a significant portion of the stomach, leaving a banana-shaped section.

○      Adjustable Gastric Banding: Places a band around the upper part of the stomach, creating a small pouch that restricts food intake.

○      Biliopancreatic Diversion with Duodenal Switch (BPD/DS): Removes a large portion of the stomach, bypassing more of the intestine and changing gut bacteria.

These procedures can lead to significant weight loss and improvement or resolution of obesity-related conditions. However, they're not without risks, and lifestyle changes are still necessary after surgery to maintain weight loss and overall health.

Final Thoughts on Morbid Obesity

Morbid obesity is a complex condition with a mosaic of potential causes, and its treatment requires a nuanced, individualized approach. While weight is the tangible aspect we often focus on, the intangible aspects, like mental well-being, self-worth, and holistic health, are equally crucial. As research advances and our understanding deepens, the hope is for more accessible, effective, and compassionate avenues to support those on their journey towards better health.
