I've been seeing Dr. Rivas Weight Loss Clinic off and on at 55 Kensington Pkwy, Abingdon, MD 21009, since 2004. The staff at this location are very compassionate, friendly, and accommodating. Dr Rivas has great bedside manners, very friendly strikes up a casual conversation that makes you feel very welcomed, I met with Dr. Rivas, in 2004, I highly recommend Dr. Paul Rivas, as your professional weight loss / control consultant. During the Covid phase, I gained quite a bit of weight, 65 pounds. I've had a difficult time trying to shed this extra weight, I've decided to visit Dr Rivas Weight Loss Clinic on September 4, 2024. At the time of my initial visit, I weighed 227 pounds at a height of 5'9". After 3 months of consultations with the Clinic PA's, I've lost 62 pounds, my weight is currently at 165 lbs, my target weight is 155 to 160 lbs, almost there and should make this goal after the Holidays Dinners.

Attached is the before and after photo, the before taken on September 4th, 2024 and the after picture taken on December 23rd, 2024, I feel soo much better now, I have more energy, I do not tire as easy, and my clothes fit much more comfortably now. A big thank you to the Rivas medical weight loss staff and the PA's.

The experience at Rivas has been great. The entire staff are so nice. I love how you are not there for so long how you normally would be at a doctors office. The longest I’ve been there is probably 30-40 min from check in to check out. Definitely would recommend to others and will go back again.

Description

Our patients often tell us they see the most weight loss early in their phentermine treatment—sometimes within the first few weeks. While results vary from person to person, many are surprised by how quickly the scale starts to move. We don’t rely on gimmicks or guarantees—just real stories and real outcomes. Come see what your journey could look like.

Many of our patients report noticeable weight loss within the first two weeks of starting phentermine. Some have shared losing between 5 to 10 pounds during this initial period, especially when combining the medication with dietary changes and increased physical activity. However, individual results can vary based on factors like starting weight, metabolism, and lifestyle habits.

Clinical studies support these experiences, indicating that phentermine users can lose approximately 3–5% of their body weight over several weeks to months. For instance, a study found that participants lost an average of 7.1 kg (about 15.7 pounds) over 14 weeks when using phentermine alongside lifestyle modifications.

It’s important to note that while some individuals experience rapid initial weight loss, sustainable results are best achieved through consistent healthy eating, regular exercise, and ongoing medical supervision.
Effects on Weight Reduction and Safety of Short-Term Phentermine Administration in Korean Obese People

Phentermine may be a suitable option if you’re:

  • Seeking an affordable, short-term weight loss solution
  • New to stimulant medications 
  • Looking for rapid results 

However, phentermine is not recommended if you: 

  • Are currently taking other stimulant medications (e.g., ADHD treatments like Adderall
  • Have a history of heart disease, stroke, arrhythmias, or uncontrolled high blood pressure 
  • Are pregnant, planning to become pregnant, or breastfeeding 

If you have chronic kidney disease, phentermine may still be considered if cleared by your nephrologist. 
If you have Glaucoma, phentermine may still be considered if cleared by your ophthalmologist. 
Always consult with your healthcare provider to determine if phentermine is appropriate for your individual health needs. 

  • Lots of energy 
  • Dry mouth 
  • Insomnia 
  • Constipation 
  • Moments of feeling hot and sweaty 
  • Irritability 

If you have been on phentermine (or any stimulant medication like for ADHD) you may have built up a tolerance to the effects of the medication. We recommend you consider trying Semaglutide or Tirzepatide.

We do not process any insurance. Unfortunately, most insurance companies refuse to cover medical weight loss, but we are happy to provide invoices for reimbursement if your insurance does. Some patients are able to get reimbursed for the visit.
