My father started loosing weight in 2016-17 and lost 10-12 kgs when he had 80-82kgs weight. He received medication for
vitamin D. During diagnosis a stone was found in his gall bladder which was surgically removed in 2018. Subsequently he lost further weight till his weight stabilized. But recently he is again loosing weight and the most recent weight is 64.5 kg. He is also suffering from weakness and at times even unable to stand up properly.
Due to removal of his gall bladder, his diet has also undergone changes like no milk, more fruits, less chapattis. He is also having acidity related issues and uneasiness.
