Talk to Dietitian/Nutritionist on Weightgain.TSH7.5/CEA 3.5

AOA, My Mother is getting weight gain despite of walks and food control (Taking bread margarine in morning, salad in lunch and normal food in dinner) in last 4 months. Her BMI is approx. 36 (Weight is depositing on Hip/thigh/Belly Area). She is HTN+ taking Atenolol 50mg QD. i did Lipid profile, RFT with sc/electrolytes,LFT,CBC,CA-125 Which were good. Only CEA 3.5, AND TSH 7.4, URIC Acid are raised. Urine/CE have some UTI indications and cranmax is prescribed by dr. Did Abdominal USG which was good. Now having said all, 2 questions. 1- WHY CEA raised, is this a threat? 2-) treatment of TSH high (possibility thyroxine dosage of 8 micrograms/kg per day) Looking for a single doctor who may help with all the history above mentioned. Finding a right doctor at right time is a blessing .. hope this may help! Thank You. UMER.
