Have there been any new discoveries for treating overweight?

Add answer

The treatments that have been developed so far are not applicable to the majority of patients but rather to small groups of people. To date, there are five drugs in the market which may be beneficial to treat and prevent overweight.

Unverified Answer

Does overweight run in families?

Add answer

Significant heterogeneity exists among the current body-mass indexes of parents and children in this large, world-wide twin population. Because of this heterogeneity, it becomes difficult to draw conclusions about the heritability of overweight, due to differences in the relationship of parents and children of any given set of siblings.

Unverified Answer

What are common treatments for overweight?

Add answer

The treatment of overweight and obese persons is highly complex and not understood by many physicians; most overweight people will succeed in reaching a target body weight with the most conservative lifestyle recommendations and little or no diet.

Unverified Answer

What causes overweight?

Add answer

The excess weight of many adolescents is associated with high levels of fatness, abdominal obesity and impaired physiological function, which can be partly explained by low levels of physical activity. It may be prudent to promote physical activity to the extent possible, with the potential to protect overweight adolescents from high levels of body fatness and poor physiological function.

Unverified Answer

What is overweight?

Add answer

Overweight is a problem for a significant number of children and is increasing in the USA. It is important to understand the factors that contribute to excess body weight gain, including family and community factors (e.g., social environment) and individual factors (e.g., genetics, age, gender).

Unverified Answer

Can overweight be cured?

Even though the data suggests improvements after an initial phase of weight control, the weight of these patients did not return to their previous levels after 12months.

How many people get overweight a year in the United States?

Add answer

Over time, the proportion of US adults who were overweight in 2002 declined from 31.3% to 27.7% in 2006. There were more men than women with a BMI greater than or equal to obesity in 2005 than in 2002 or 2006, but the proportion of adults with body mass indexes of greater than or equal to obesity has remained stable over time.

Unverified Answer

What are the signs of overweight?

Add answer

Signs of overweight and obesity may vary widely from person to person. Overweight is often overlooked because the signs are often subtle and non-specific. In some instances, weight loss is the most visible symptom of diabetes mellitus. If this is the case, the diagnosis will be missed, especially if weight loss in this condition is precipitated by obesity-related diseases or conditions that are either related or associated with obesity. Thus, early and aggressive diagnosis of diabetes, hypertension and obesity is essential so that the diseases may be treated promptly and adequately.

Unverified Answer

How serious can overweight be?

Add answer

Obesity can lead to many serious health problems which can only be alleviated by changes in lifestyle behaviours. Some of the major health problems associated with obesity include diabetes, cardiovascular disease, osteoarthritis, sleep apnea, hypertension and many others. The prevalence of overweight was 25.2% in an Australian sample in 2009. While obesity is associated with high morbidity and mortality, there is a lack of awareness in the community. Awareness campaigns highlight the physical and mental health issues associated with overweight.

How does amiloride pill work?

Add answer

Oral amiloride treatment is effective in improving both glycemic control and the risk of hypoglycemia in severely obese nondiabetic patients with type 2 diabetes in whom diet treatment alone has been ineffective.

Unverified Answer

What are the latest developments in amiloride pill for therapeutic use?

Add answer

Amiloride pills have more and more indications. As of 2015, the latest one being in the treatment of heart failure and chronic kidney disease. As mentioned in the article, if a patient does not tolerate the contraindications, or does not have it available in his region (e.g. as a foreign drug) then he can definitely get it from abroad.

Unverified Answer

Does amiloride pill improve quality of life for those with overweight?

Add answer

Recent findings of this study suggest that amiloride may improve quality of life in some people who are overweight, especially those who are mildly obese. We recommend that people with chronic illnesses should undertake trials of amiloride during an exacerbation in order to prevent worsening of their condition. This is feasible with amiloride because the drug also lowers blood pressure, and is thus effective in treating patients with hypertension. Therefore, in some cases amiloride can be used to prevent exacerbations and even a potential deterioration in the condition.
