What Is Muscle Loss?
Muscle loss (sarcopenia) is the gradual decline in muscle mass and strength. It can make everyday activities—like walking, lifting, or climbing stairs—more difficult and increases the risk of falls and dependence.
Common Causes and Risk Factors
Aging - after age 30 you lose up to 5% of muscle mass every decade
Lack of activity or prolonged bed rest
Poor diet or inadequate protein/calorie intake
Chronic diseases (diabetes, heart or liver disease, dementia)
Certain medications (appetite suppressants like Ozempic)
Hormonal changes (low testosterone or estrogen)
Signs and Symptoms
Weak grip or trouble opening jars
Difficulty climbing stairs or rising from a chair
Noticeably smaller arms or legs
Fatigue after light activity
Poor balance or more frequent falls
How Dr. Nghia Nguyen Diagnoses?
Dr. Nguyen uses a step-by-step approach:
Medical History and Physical Exam
He reviews your pain pattern (onset, location, duration), diet, alcohol or NSAID use, stress levels, and any red-flag symptoms (weight loss, bleeding, vomiting).
Laboratory Tests
We draw blood to check for anemia, H. pylori antibodies or antigen, liver function, pancreatic enzymes, and inflammation markers.
Imaging Studies
Abdominal ultrasound to evaluate the gallbladder, liver, kidneys, and pancreas.
CT scan of the abdomen if complications (e.g., pancreatitis, masses) are suspected.
Endoscopy (If Needed)
An upper GI endoscopy allows direct visualization of the esophagus, stomach, and duodenum to detect ulcers, gastritis, or other lesions and obtain biopsies.

Frequently Asked Questions
Is muscle loss a sign of dementia?
People with early dementia may move less or eat poorly, which can lead to muscle loss.
Does Ozempic cause muscle loss?
Ozempic can produce overall weight loss, including some muscle. A balanced diet and strength training help protect muscle mass.
How can I prevent muscle loss while taking Ozempic?
Incorporate regular strength training and include a good source of protein with every meal. Dr. Nguyen will help you design the right plan.
Can muscle loss be reversed?
Yes. With targeted exercise, proper nutrition, and medical guidance, many people rebuild strength and muscle size.
How is muscle loss diagnosed?
We combine your medical history, strength and walking tests, blood work, and sometimes imaging (DEXA scan or ultrasound) to measure muscle mass.
When should I see a doctor in Houston about muscle loss?
If you notice weakness, frequent falls, or shrinking arms or legs, it's time for an evaluation with Dr. Nguyen.
Are there supplements for muscle loss?
