This is Dr. David
she needs an ultrasound of the abdomen to see if she as ascities fluid in her abdominal cavity
fat is different from fluid in the abdominal region and is not the same as lymphatic fluid.
lymphatic fluid is in the subcutaneous tissues and is due to damaged lymphatic channels from trauma or surgery.
ascities fluid is fluid in the peritoneal cavity in the abdomen outside of the organs and can be due to inflammation or irritation of the peritoneal cavity. this ascities fluid can be drained out by a needle drain.
lymphatic fluid can't be drained by a needle.
for lymphatic fluid, this can be helped by lymphatic fluid massage therapy to push out the fluid,
also compression stockings and compression wear around the waist can help push lymphtic fluid out of the area.
an ultrasound of the abdomen can check if it is ascities fluid or lymphatic fluid
let me know if you have questions.
