Yes, it is definitely worth considering becoming an obesity specialist. Obesity is linked to over 66 diseases and the list is constantly growing. This "tree of diseases" has many branches, such as ischemic heart disease, osteoarthritis, cerebrovascular accidents, hernias, diabetes mellitus, and cholecystitis, among others. However, current medical practices are often limited to treating individual branches of this tree rather than addressing the root cause - obesity. Bariatric medicine, which focuses on weight loss as a means of reducing the morbidity and mortality associated with these diseases, is an emerging field with a bright future. By treating obesity, a bariatric physician can potentially provide a "one-stop cure" for a patient against multiple ailments, rather than the patient having to visit numerous specialists. In conclusion, becoming an obesity specialist can be a promising career path given the growing awareness of the importance of weight management in overall health.

Obesity is linked to numerous comorbidities, including mechanical and cardio-metabolic complications. For patients with mechanical complications, weight loss is often necessary but may require impetus beyond exercise due to pains and stiffness. In these cases, diet and physiotherapy may be recommended. Patients with cardio-metabolic complications, on the other hand, typically require a combination of dietary changes and medications for managing conditions such as diabetes, hypertension, and dyslipidemia. Step-down diets are often preferred in these scenarios, and exercise is also recommended under the supervision of an exercise physician. Prior to starting a weight loss program, a thorough assessment should be conducted to rule out any hidden cardiovascular or mechanical issues. Eating disorders and stress eating should be addressed by a clinical psychologist, while sleep apnea should be diagnosed and treated alongside lifestyle changes and medications. In cases where fibrosis and cirrhosis are a concern, fibro scans and MR elastography may be required to tailor treatment accordingly. Overall, a comprehensive and personalized approach is needed to manage obesity effectively with various comorbidities.

Yes, in addition to diet, exercise, and medicines, yoga can be a helpful tool in managing obesity. Practicing yoga, pranayama, and chakra-based micronutrient management can improve compliance and perseverance, which are often major hurdles in obesity treatment. Yoga asanas can also aid in injury prevention during exercise and improve outcomes. Overall, incorporating yoga into an obesity management plan can improve the quality and effectiveness of treatment.
