ABOUT PLENITY

Plenity is a new weight loss pill as of Fall 2020 and is only available via prescription from doctors. It’s actually marketed as a “medical device” rather than a drug because it doesn’t affect the body’s hormones. Plenity can be used to treat overweight (BMI>25), obesity (BMI>30), and even lower levels of excess body weight than other medications.

How Plenity Works 

The Plenity weight loss pill is made from cellulose and citric acid. The patient ingests 3 tablets and 16 oz of water before lunch and dinner. Plenity tablets swell 100 times their original size, taking more space in the stomach and gives the user a feeling of fullness (satiety). After that it moves through the intestines, and passes with bowel movements. 

Plenity’s Side Effects 

Since Plenity isn’t absorbed by the body, side effects are less common than other weight loss medications. Possible side effects of Plenity include: 

  • abdominal pain
  • bloating
  • constipation
  • cramping
  • diarrhea
  • gas
  • irregular bowel movements

How Phentermine weight loss drug affects the brain

ABOUT PHENTERMINE

Phentermine is a stimulant-based appetite suppressant. It increases metabolism and acts directly on the appetite centers of the brain, an area called the hypothalamus. Used with diet and exercise, phentermine treats overweight and obesity. As on the most common weight loss drugs, phentermine is one of the least costly and is safe for long-term use

How Phentermine Works 

Phentermine stimulates the central nervous system. As a result, it increases your heart rate and blood pressure, then decreases your appetite.

Phentermine’s Side Effects

For most people, phentermine increases energy so its used with caution on patients with anxiety. It is also not safe to use in many patients with heart disease and diseases of rapid heart rate. Common side effects of Phentermine includes: 

  • Constipation
  • Dry mouth
  • Increased heart rate
  • Nervousness
  • Tingling or prickling sensation
  • Sleeplessness

ABOUT CONTRAVE

Contrave is a perscription-only weight loss drug that decreases appetite. It’s particularly helpful for cravings and food addiction. Containing two medicinces, bupropion and naltrexone, Contrave is FDA approved for long-term use.  

How Contrave Works 

Contrave stimulates the hunger and reward center of the brain. It raises levels of dopamine to reduce hunger and control cravings. Contrave doesn’t affect the metabolism, so it’s safe to use in people with heart disease.

Contrave’s Side Effects 

Common side effects of Contrave include: 

  • constipation
  • dry mouth
  • diarrhea
  • dizziness
  • headache
  • insomnia
  • nausea
  • vomiting

PLENITY VS PHENTERMINE VS CONTRAVE

There is no right medication for everyone.  Choosing the best medication, device, or combination of both depends on the person. Your obesity medicine specialist will combine medication, diet, behavior change, and physical activity to optimize not just losing weight, but also weight loss maintenance.
