Causes of Dehydration

If you're an average adult, every day you lose more than 10 cups (close to 2.5 liters) of water simply by sweating, breathing and eliminating waste. You also lose electrolytes — minerals such as sodium, potassium and calcium that maintain the balance of fluids in your body. Normally, you can replenish what you've lost through the foods and liquids you consume, even when you're active.

Causes include:-

  1. Lack of adequate water intake, because you're sick or busy, or because you lack access to potable water when you're traveling, hiking or camping, mouth sores, uncosciousness etc.
  2. increased losses due to Diarrhea, vomiting, excessive sweating in hot and humid conditions, fever, diabetes due to increased urination, excessive respiration like in pneumonia, burns, etc.
  3. Renal failure, addison’s disease and other similar conditions too can lead to increased urination thus leading to dehydration.
  4. Certain medications — diuretics, antihistamines, blood pressure medications and some psychiatric drugs — as well as alcohol also can lead to dehydration, generally because they cause you to urinate or perspire more than normal.

As the patient becomes more dehydrated - irrespective of the cause - symptoms include: weight loss (2-3 pounds per day), dryness of the mouth, decreased production of saliva, impaired swallowing, shrinkage of tissue, dry/wrinkled skin, headache, raised pulse, shrunken eyes, and fever. As dehydration and salt loss progresses, blood output from the heart decreases, while sweating may cease entirely. Body temperature then rises precipitously. If urination falls too low in response to the dehydrated condition of the body, the kidney becomes unable to excrete toxic waste products. The combined effect of high temperature, reduced blood output and kidney malfunction is irreversible shock and death. Typically this occurs in previously healthy adults after a water loss of about 12-15 liters (3-3.75 gallons), but may occur much more quickly in the very young or very old.

Causes of Hair Loss

The common causes of hair loss include:-

  1. A stress like surgery, severe illness etc. For example, about 3 or 4 months after an illness or a major surgery, you may suddenly lose a large amount of hair. This hair loss is related to the stress of the illness and is temporary. This is also known as Telogen Effluvium.
  2. Hormonal problems like low thyroid, elevated testosterone, and diabetes and PCOS (Polycystic Ovaria Syndrome) can lead to hair loss.
  3. Several inflammatory skin conditions, such as eczema, seborrhea, and psoriasis, cause patches of hair loss with red and scaly skin underneath. Fungal scalp infections (also called ringworm) and bacterial infections of the hair roots (folliculitis) can also cause similar problems.
  4. Tight hairbands can cause local trauma & thinning simply by breaking off the hairs at their base. Some chemical hair treatments damage the follicles or the hair itself. Insects that attack the hair (like lice or scabies) can cause hair loss either by directly breaking the hair or by causing the person to scratch, which in turn damages the hair.
  5. In male- and female-pattern baldness, the time of growth shortens, and the hairs are not as thick or sturdy. With each growth cycle, the hairs become rooted more superficially and more easily fall out. Heredity likely plays a key role.
  6. Having inadequate protein or iron in your diet or poor nourishment in other ways can cause you to experience hair loss. Fad diets, crash diets and certain illnesses, such as eating disorders, can cause poor nutrition.
  7. Certain drugs used to treat gout, arthritis, depression, heart problems and high blood pressure may cause hair loss in some people. Taking birth control pills also may result in hair loss for some women.
  8. Psychological problems may lead to a condition called Trichotillomania in which people pull out their hair, leading to hair loss.

Benefits Of Breastfeeding

Breastfeeding is the best form of nutrition for babies. Breastmilk provides all the nutrients a baby needs. In the UK it is recommended that babies fed by breastfeeding alone for their first six months. The recommended age for starting to add in solid foods ('weaning') is six months. Below are some benefits of why 'breast is best' for most babies and mothers.

What are Benefits of Breastfeeding?

  • Breast milk is the most complete form of nutrition for infants. A mother's milk has just the right amount of fat, sugar, water, and protein that is needed for a baby's growth and development.
  • Most babies find it easier to digest breast milk than they do formula.
    There is some evidence that children who are breast-fed are less likely to be obese when they are grown up.
  • There is also growing evidence that babies who are breast fed are less likely to develop diabetes and heart disease in later life.
  • Many mothers also get emotional benefits from breastfeeding because of the closeness of this interaction with the baby and from the satisfaction of helping to nourish their babies.
    Breastfeeding can help a mother to bond with her baby. Physical contact is important to newborns and can help them feel more secure, warm and comforted.
  • Some of the nutrients in breast milk also help protect an infant against some common childhood illnesses and infections, such as diarrhoea, middle ear infections, and certain lung infections.

Are there cases in which it is better not to breastfeed?

  • A woman with certain health conditions, such as HIV or active tuberculosis, should not breastfeed because she risks giving the infection to her infant through her breast milk.
  • Women who actively use drugs or do not control their alcohol intake, or who have a history of these situations, may also be advised not to breastfeed.
  • Certain medicines, including some mood stabilizers and migraine medicines, can also pass through the breast milk and cause harm to the infant.
