About Semaglutide Treatment at Family First
Semaglutide is an FDA-approved GLP-1 receptor agonist used in the management of type 2 diabetes and, in eligible adults, for medically supervised weight management. It works by mimicking natural hormones that signal fullness, helping reduce appetite over time. At Family First, this medication is administered under provider supervision following a thorough eligibility evaluation and is most effective when combined with lifestyle changes. Our
providers include Dr. Qanwar Sidhu, who holds a focused specialty in weight management and diabetes, and PA-C Simarjeet Manocha, who brings dedicated expertise in chronic disease and metabolic care. They will review whether this treatment is right for you.

Frequently Asked Questions
What Kind of Weight Loss Program Does Family First Offer?
Family First offers physician-supervised care tailored to each patient's health profile. The program includes lab-based evaluation, personalized nutrition and lifestyle guidance, and a medical review of medication options such as GLP-1 therapy for eligible adults. A licensed provider builds the plan around the patient's health history and adjusts it during follow-up visits.
Is Semaglutide Available at This Clinic in Lancaster, CA?
Yes, Family First provides this medication following a provider-conducted eligibility review. Not every patient is a candidate, so a consultation and health evaluation are required before any medication is considered. When it is appropriate, the provider supervises treatment and combines it with lifestyle changes.
Do I Need an Appointment, or Can I Walk In?
We welcome walk-ins, so an appointment is not required. We also offer same-day and advance appointments for new and established patients, which can be scheduled by calling (661) 341-3800. Same-day availability varies, so we recommend calling ahead when timing matters.
Can I Use Insurance for Weight Management Visits?
We accept insurance and welcome self-pay patients. Coverage for these services varies by plan, so we recommend calling ahead to confirm your benefits before your visit. Verifying coverage in advance helps you understand any out-of-pocket costs before treatment begins.
How Is Weight Loss Connected to Diabetes Care at Family First?
Excess weight can contribute to insulin resistance and elevated blood sugar, and losing weight may support better blood sugar control.
