The symptoms as mentioned in your post are not different, but are related to each other.
The problem of hard stool can be due to:
1. Functional cause- due to decreased gastric motility
2. Irritable bowel syndrome- constipation
3. Less consumption of fiber rich foods
4. Less fluid intake
5. Prolonged use of certain medications.
6. Hormonal & Metabolic causes, etc.
Hair fall has also its etiology in stress, hormonal & nutritional factors.
Nausea after moderate exercise or motion is due to dietary deficiency of certain essential nutrients, fluid & electrolyte imbalance
These factors are also responsible for difficulty in getting sleep at night, due to which you get sleep easily during day.
Presence of excess hair around areola & increased sensitivity in the nipples are attributed to hormonal factors.
Though symptomatic relief can be obtained by intake of Laxatives and multivitamin
supplements, as long as the underlying cause is not treated, symptoms will keep recurring.
So, kindly consult a Gastroenterologist
& get a proper physical examination done.
Investigations like complete blood count
scan of abdomen, Colonoscopy
& contrast studies will be helpful to rule out any pathological cause for your symptoms.
There is no need to worry, you will be fine.
Till then, take healthy nutritious diet, exercise regularly and keep away stress.
Wishing a good health.
