Hello,
Welcome to icliniq.com.
I completely understand that you must be very concerned and upset about your mother's health. I am sorry to hear that she has been admitted to the hospital because of dehydration. First of all, thankfully, her endoscopy (attachment removed to protect patient identity) did not show any nasty or ominous findings. It showed normal esophagus and a few erosion in the stomach and duodenum, which are likely due to H.pylori infection as confirmed by positive RUT (Rapid Urease Test).
Yes, these erosions in the stomach and duodenum can define her current symptoms. In medical terms, we call this a peptic ulcer disease (PUD). PUD can cause abdominal pain, stomach burning, vomiting, decreased appetite, and some serious case bleeding. Since these erosions are occurring secondary to H pylori infection, treatment of H pylori will cause the resolution of her erosions and symptoms.
Your query of other investigation to look for other causes. Well, since her TSH (thyroid-stimulating hormone) is high, which shows the thyroid gland is hypo functioning (low functioning) medically termed as hypothyroidism. Her weakness, loss of energy (apathy) could be related to hypothyroidism. This will also go away once treatment starts to achieve the target TSH level in the coming few weeks. The target TSH level is less than 10 for her age.
The pancreatic disorder usually comes with severe abdominal pain, which I did not find in her history. I do not think that she has any brain or nerve problem. Otherwise, she would have complained of headache, blurring of vision, loss of consciousness, or altered behavior. None of these symptoms present, as you mentioned.
For H.pylori treatment, she is supposed to take a 14 dose of antibiotics, which frequently causes gastric upset such as vomiting, nausea, and diarrhea. Almost similar symptoms for which she has been brought in the hospital. I want that once she is stable enough to take oral medicines, we should defer the treatment. However, a proton pump inhibitor (PPI) such as Esomeprazole 40 mg twice daily half an hour before meals can be given to suppress her stomach acid production and heal the erosions fully. I hope her symptoms will vanish in the next 48 hours of the start of PPI.
Plus, I suggest her to take tablet Ondansetron 8 mg (antiemetic) thrice daily half an hour before meals. This medication would treat her nausea, vomiting and improve her indigestion and appetite.
I suggest to start her tablet Thyroxine 50 mcg (thryroid tablet) before breakfast daily and would increase the dose based on her symptoms improvement and TSH monitoring. If an internal medicine physician has already given you a prescription for her hypothyroidism, I urge you to follow that. Otherwise, you can follow my recommendation for her hypothyroidism. Please find the treatment plan below.
I hope this helps.
