  • Feeling thirsty
  • Dark yellow and strong-smelling urine

  • Becoming irritable
  • High fever
  • Drowsiness or sleeping more than usual

The symptoms that should be taken to the hospital should be:

  • If you can’t turn your head even if you stand,
  • Breathing fast

  • The soft part of the top of the head is slightly depressed.
  • Dry mouth
  • Dark yellow urine or no urine in the last 12 hours
    Cold and clammy hands and feet

Treatment of Dehydration

Dehydration can be treated at home if there are no serious symptoms.

Dehydration treatment is to replace the water and salt loss from the body. If dehydration occurs, plenty of water, oral saline (Orsaline), and fluid intake are recommended.

Liquid foods include boiled water, canned water, rice starch, and soup. Apart from this, fruit juice can be diluted with pure water and consumed. In addition to these foods, you should continue to eat normal food.

If you don’t have packaged food saline at hand, you can make food saline at home.

Severe dehydration may require hospitalization and intravenous saline.

Special precautions for children

After treating dehydration in children, it is important to give the child adequate fluids to prevent rehydration. Some suggestions in this regard are:

Do whatever

  • Continue to breastfeed the baby. For any reason, formula or formula feeding should be continued. Try to feed the baby more than usual during this time. Try feeding little by little.
  • Give small amounts of water to small children who are on formula or solid foods.
  • Continue to feed the baby normal food. It is better to feed little by little rather than give too much food.
  • Give the child oral saline, such as saline, to compensate for salt, water, and sugar deficiency in the body.

What not to do

Do not dilute the formula and feed it to the baby. The formula should be prepared and fed according to the instructions written on the container or on the accompanying paper.
Avoid giving fruit juices and soft drinks bought from the market to small children. These can increase diarrhea and vomiting problems in children.

Causes of dehydration

Reasons that can easily lead to dehydration include:

  • Vomiting and diarrhea
  • Drinking less water than is required
  • Excessive sweating
  • Staying in the sun for a long time
  • Having a long-term condition that causes excessive urination or sweating. For example, diabetes and kidney disease
  • An increase in body temperature above 38 degrees Celsius or 100.4 degrees Fahrenheit
  • Taking medicine to remove water from the body. For example, diuretics
  • Excessive drinking

Children and elderly people are at higher risk of dehydration.

Home Remedies to Prevent Dehydration

The easiest and most effective way to prevent dehydration is to drink plenty of water or liquid food as soon as you experience any symptoms of dehydration.

  • If it is difficult to drink a lot of water at once or if you feel nauseated, then you should drink small amounts of water repeatedly. In children, feeding water and liquid foods with a spoon may facilitate swallowing.
  • Try to drink as much water as possible during the day until the colour of your urine is clear and light yellow, i.e., normal.
  • Avoid working in extreme heat or strong sunlight for long periods of time. If it is not possible to avoid such work, try to drink as much water as possible during this time. You can take a bottle of water with you while going to work.
  • Diarrhea, vomiting, and excessive sweating increase the risk of dehydration. In these cases, eat more water and liquid food.
  • Avoid foods, drinks, and caffeine with excess sugar. Coffee and tea contain caffeine. Avoid drinking alcohol.

There are a few things to keep in mind when caring for people who have no idea how much water they’re drinking throughout the day. For example-

  • Make sure the person is drinking enough water at each meal.
  • Eat foods that contain more water. For example, soup, watermelon, and canned water
  • Presenting drinking water as a social practice, like having tea together.

what are the cardiac effects of dehydration:

In summary, knowing how dehydration affects the heart is essential to preserving good cardiac health. Knowing and mitigating the hazards associated with dehydration, such as impaired blood circulation and heightened cardiovascular strain, enables people to take preventative action to ensure adequate water consumption and heart health. Making hydration a priority is important for supporting cardiovascular health in general as well as for satisfying appetite.
