Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain the symptoms of hard stools and lack of bowels for 2 days followed by liquid stools on third day along with nausea, bloating and vomiting seems to be due to Constipation and can occur due to causes like changes in the regular diet that you take, low fibre containing diet,less physical activity,side effects of any medications, stress,
hypothyroidism while if it is recurring condition it can also be due to chronic diseases like
Irritable Bowel Syndrome etc..
I would suggest you to
consult a Gastroenterologist and get evaluated and he can advise you to take laxatives like
Polyethylene glycol and lubricant like Castor oil..
You can also be advised to take Lactulose or Psyllium husk as they are high fibre components..
Prescription medications like
Lubiprostone can also be advised..
Along with it take more of fibres in diet..
Green leafy vegetables, fruits can increase bulk of urine..
Drink plenty of water..
In case if still there is no relief then the physician can advise investigations like Colonoscopy, Barium swallow, etc to rule out other causes and treat accordingly..
Hope this information helps..
Thanks and regards.
