Effective Treatment & Services
Clinic Consultation & Symptom Management:
At American Medical Group, we provide comprehensive evaluations for a wide range of digestive health concerns. Whether you’re dealing with chronic symptoms or seeking answers for new issues, our team takes a collaborative approach, working alongside your primary physician to develop a personalized treatment plan. With fast appointment availability, we ensure you get timely care without unnecessary delays.
Endoscopy & Colonoscopy:
We offer both diagnostic and preventive procedures, including upper endoscopies and colonoscopies, through our onsite facilities or affiliated partners. These procedures are essential for colorectal cancer screenings and for investigating symptoms like abdominal pain, gastrointestinal bleeding, or unexplained weight loss. Throughout the process, we prioritize patient comfort and maintain the highest standards of safety.
Liver Health & Metabolic Evaluations:
Our team provides in-depth assessments of liver function, addressing conditions such as fatty liver disease, hepatitis, and alcohol-related liver damage. By combining medical therapies with personalized lifestyle recommendations, we help patients improve liver health and prevent disease progression through proactive, target care.
IBD Management & Nutritional Support:
For patients living with inflammatory bowel diseases like Crohn’s Disease and Ulcerative Colitis, we create comprehensive management plans that may include advanced medications, such as biologics. In addition, we offer dietary guidance and nutritional support to reduce flare-ups, improve symptom control, and support overall gut health.
Onsite Diagnostics & Laboratory Services:
Accurate diagnosis and timely monitoring are key to effective symptoms, track treatment effectiveness, and adjust care plans as needed. With an efficient result turnaround, we aim to keep your care process smooth and stress-free.
