Obesity – Diagnosis and Treatment
Diagnosis
Obesity diagnosis starts with a review of personal health history. Health care providers ask about past weight trends, previous attempts to lose weight, regular physical activity, and common eating habits.
They also discuss stress levels, medicines you take, and any family history of health conditions like diabetes or heart disease. A physical checkup is a key part of this process.
Providers measure height and weight, check blood pressure, and listen to the heart and lungs. These steps help show overall wellness and can reveal early signs of health risks linked to being overweight.
Body Mass Index (BMI) Calculation
Providers use BMI as a main tool for diagnosing obesity. They calculate BMI using height and weight.
Adults with a BMI of 30 or above have obesity. Higher BMI values raise the risk for heart disease, type 2 diabetes, and fatty liver.
Waist Size Measurement
Measuring waist circumference is another important step. This test shows how much fat is stored around the abdomen.
Fat in this area often raises the chances of health risks like heart disease and type 2 diabetes. A waist larger than 40 inches (about 102 cm) in men or 35 inches (about 89 cm) in women points to a higher risk.
| Measurement | Healthy Range (Men) | Healthy Range (Women) |
|---|---|---|
| BMI | Below 25 | Below 25 |
| Waist Circumference (inches) | ≤ 40 | ≤ 35 |
Additional Tests
Doctors may order blood tests to check for conditions linked to obesity, such as high cholesterol, high blood sugar, thyroid disorders, or fatty liver disease. They also look for hormone changes and signs of diabetes.
Possible Problems to Check For:
- High cholesterol
- High blood pressure
- Type 2 diabetes
- Liver concerns
- Hormone imbalances
Treatment
Changes in Food Choices
Changing eating habits is a key way to help with weight loss. Eating fewer calories is important for most people.
People often start by tracking how many calories they eat now and then set a daily limit. Common calorie goals are between 1,200 and 1,800 calories per day, depending on age, gender, and health.
Choosing foods that fill you up without adding too many calories can help you stick to a lower-calorie plan. For example, eating more fruits and vegetables is encouraged because they have a lot of fiber and water.
Healthy eating means picking lean proteins like fish, beans, or tofu, and limiting red meat, processed foods, and high-fat items. Plant-based foods, such as whole grains, fruits, and vegetables, should make up most of the diet.
Try to eat less salt and sugar, and use healthier oils in small amounts to help heart health and weight loss. Some diets cut out entire food groups, such as carbs or fats. Talk with a doctor or dietitian before starting these plans.
Drinking fewer sugary drinks, like soda or sweetened coffee, can lower calorie intake. Some people use meal replacements, like shakes or bars, for one or two meals daily. The third meal is a healthy, low-fat choice.
Meal replacements can help with quick weight loss at first, but it is important to learn healthy eating for long-term success. Healthy eating that can be continued for a lifetime is most effective.
| Strategy | Description | Example Changes |
|---|---|---|
| Reduce Calories | Eat less food overall. | Smaller portion sizes, skip snacks |
| Eat High-Volume, Low-Cal | Choose foods with more water or fiber. | Eat more vegetables, soup, broth |
| Increase Whole Foods | Choose less processed items. | Whole fruit, beans, brown rice |
| Limit Sugary Drinks | Reduce liquid sugar intake. | Water, unsweetened tea instead of soda |
| Use Meal Replacements | Swap meals for pre-made options occasionally. | Protein shakes or meal bars for lunch |
Being More Physically Active
Physical activity helps with weight loss and prevents regaining lost weight. Adults should aim for at least 150 minutes of moderate exercise each week. Moderate exercise includes activities like brisk walking, biking, or swimming.
For beginners, it helps to add activity slowly. Over time, more exercise can improve heart health and burn extra calories. Even light activity, such as standing up more or walking during breaks, can help.
Many people try to reach 10,000 steps per day using a step counter. Adding movement to daily life is helpful. Taking the stairs, parking farther away, or doing house and yard work all count. Physical activity also improves mood and supports overall health.
Tips for Success
- Set small, achievable goals, such as ten more minutes per week.
- Make exercise part of your daily routine, like after-dinner walks.
- Choose activities you enjoy, so it feels less like a chore.
Adopting New Habits for Success
Changing behavior is a key step in managing weight. Look at your routines and find what leads to unhealthy choices. Stress, boredom, or emotions can lead to overeating.
Counseling or therapy can help people understand why they eat in certain ways and teach new habits. Counseling may be one-on-one or in a group. Therapists or counselors teach skills like:
- Recognizing your eating triggers.
- Setting small, realistic goals.
- Keeping food and activity logs.
- Learning new ways to handle stress.
Support groups also help. Sharing stories and working toward goals with others can provide encouragement and ideas. Behavior change takes time, and setbacks can happen. Support from others can help you stick to new routines.
| Tool | How It Helps |
|---|---|
| Food journal | Tracks eating patterns and choices. |
| Goal setting | Focuses on small, achievable steps. |
| Group sessions | Gives support and accountability. |
| Cognitive therapy | Addresses emotions and thought patterns. |
| Stress management | Reduces emotional eating. |
Prescription Options for Weight Loss
If diet, exercise, and behavior changes are not enough, doctors may suggest weight-loss medicines. These medications work best when used with lifestyle changes. These medicines may help you feel less hungry, feel full longer, or absorb less fat from food.
Each one works differently, and side effects can occur. Doctors choose a medicine based on your health history. Not everyone responds the same way, and some weight may return if the medication is stopped.
| Medication Name | How It Works | Possible Side Effects |
|---|---|---|
| Lipase inhibitor | Blocks fat from being absorbed | Stomach cramps, oily stools |
| GLP-1 receptor agonist | Reduces appetite | Nausea, diarrhea |
| Antidepressant-opioid antagonist combination | Affects brain chemicals tied to appetite | Dry mouth, headache |
| Sympathomimetic with anticonvulsant | Reduces appetite | Increased heart rate |
These medicines are FDA-approved and are usually for people with a BMI of 30 or higher, or those with a BMI of 27 with certain health issues.
Non-Surgical Stomach Procedures
Some newer weight loss procedures do not need surgical cuts. Doctors use tools that go into the stomach through the mouth. These options can help people who haven’t lost weight with other methods.
Types include:
- Endoscopic Sleeve Gastroplasty: Doctors place stitches inside the stomach to make it smaller from the inside.
- Intragastric Balloon: Doctors put a small balloon into the stomach and fill it with fluid. The balloon helps you feel full faster and is removed after up to six months.
These treatments may help with weight loss when combined with changes in eating and activity habits. Not everyone qualifies, so a doctor will decide if these are right for you.
| Procedure | What Is Done | How It Works |
|---|---|---|
| Endoscopic sleeve gastroplasty | The stomach is stitched to make it smaller. | Less space for food. |
| Intragastric balloon | Fluid-filled balloon in stomach. | Makes you feel full sooner. |
These choices do not involve surgical incisions, so recovery time is shorter. However, some side effects or risks may still occur.
Surgical Solutions for Weight Reduction
Doctors may recommend surgery in some cases. These are called bariatric procedures. Surgery is usually for people with severe obesity or when other treatments have not worked.
Three common surgical procedures are:
- Adjustable Gastric Banding: Doctors place an inflatable band around the top part of the stomach. This creates a small pouch that gets full quickly.
- Sleeve Gastrectomy: Doctors remove part of the stomach to make it much smaller. People feel full after eating a small amount.
- Gastric Bypass (Roux-en-Y): Doctors make the stomach smaller and bypass part of the small intestine. This reduces portion size and means the body takes in fewer calories and nutrients.
| Surgery Type | How It Works | Possible Risks |
|---|---|---|
| Adjustable gastric band | Band makes the upper stomach a small pouch. | Infection, band problems |
| Sleeve gastrectomy | Removes most of the stomach. | Leaks, vitamin shortage |
| Gastric bypass (Roux-en-Y) | Small pouch & bypass intestine | Ulcers, dumping syndrome, deficiencies |
After surgery, people need to take vitamin and mineral supplements, eat slowly, and follow special diets. Surgery can lead to fast weight loss and improve health problems such as high blood pressure or type 2 diabetes. A thorough discussion with a doctor is needed to decide if surgery is the right step.
Other Ways to Manage Weight
Other actions can support weight health:
- Weight Management Programs: Hospitals or clinics offer support from dietitians, counselors, and doctors.
- Health Coaching: Professionals give advice on healthy eating, exercise, and setting realistic goals.
- Medical Devices: In rare cases, doctors implant devices to interrupt signals to the stomach.
Treating underlying health issues is also important. For example, treating thyroid problems or sleep issues can help with weight loss.
Other Helpful Supports
- Stopping smoking
- Limiting alcohol
- Managing stress and mental health
Combining several treatment approaches can improve the chances of reaching and keeping a healthy weight.
Lifestyle Changes and At-Home Strategies
Making healthy changes at home can help people living with obesity. Learning about this condition helps individuals understand the factors involved, such as genetics, family background, environment, and emotional health.
Reading trustworthy sources or talking with a health professional gives useful information and support. Setting small, practical goals for weight loss and exercise helps people stay motivated.
Trying to make quick, large changes often leads to disappointment. Focusing on achievable steps—like adding extra vegetables to meals or taking short walks—helps people stay on track.
Sticking with a treatment plan can be challenging, especially when stress or low self-esteem appear. Being open with doctors or therapists about struggles allows for helpful advice and new ideas.
If someone has a tough week, they can work with their care team to adjust their goals. Involving family and friends provides extra encouragement.
People who feel supported at home are more likely to stay motivated. Talking openly with family members about health goals or joining a group focused on weight management increases accountability.
Support also helps when making changes at home, such as stocking healthier foods. Tracking progress with a simple chart or notebook gives people more control.
| Factor | Example of Action |
|---|---|
| Genetics & Family | Share goals with family, plan group activities |
| Stress & Mood | Use relaxation tools, seek emotional support |
| Self-Esteem | Celebrate small victories, join a support group |
| Environment | Make healthy choices easier at home |
