Loss of appetite in adults & seniors: Tirupati
A persistent loss of appetite (anorexia) or unintended weight loss in an adult or senior is an important medical signal that warrants doctor evaluation. Rather than simple disinterest in food, poor appetite frequently stems from underlying type 2 diabetes, kidney or liver strain, chronic anaemia, thyroid disorders, medication side effects, or silent infections. Senior Consultant Physician Dr. Vishnu Anjan Nareddy evaluates root metabolic causes with same-day laboratory testing at Nareddy Care Hospitals in Tirupati.

Common possible causes
Frequently asked questions
When is loss of appetite a serious medical concern?
If poor appetite lasts more than 2 weeks, is accompanied by unintentional weight loss, difficulty swallowing, or changes in bowel habits, it requires comprehensive physician evaluation and blood testing.
Can diabetes medications cause loss of appetite?
Yes. Metformin frequently causes metallic taste, nausea, or appetite blunting when first started or when dosages are increased. Dr. Vishnu adjusts the timing or formulation to eliminate discomfort.
What tests are recommended for loss of appetite?
A physician typically checks a Complete Blood Count (for anaemia), Kidney Function Test (creatinine), Liver Function Test (LFT), blood sugar, and thyroid TSH to pinpoint the metabolic trigger.
