Hello Your findings suggests diffuse heterogeneous liver parenchymal echotexture and it may be due to many reasons like cirrhosis,hepatitis etc. Normal liver is homogeneous in echotexture. You need proper clinical examination and further investigations. Investigations include routine hemogram,random blood sugar,complete liver function test,lipid profile,urine RE/ME,renal function test,viral markers,ultrasound of abdomen. CT scan of abdomen and elastography of liver can be done if needed. Proper treatment depend upon findings. Most likely altered liver echotexture is not related to thyroid disorder. Get well soon.
