What Are The Common Signs & Symptoms Of Autism ?

What are the Common Signs & Symptoms of Autism ?

The common signs and symptoms of autism in children include lack of eye contact, repetitive hand movement, unusual fixations on objects or events like ceiling fans, and a failure to show meaning using tone and body language. Children with autism often develop some ability to understand empathy as they grow up but the earlier you identify it and seek treatment for your child the better chance, they have at making social connections. The most important thing is that early detection is very important to give your child time to learn social skills that will make their life easier when learning about everything else going on around them. When looking for new information on autism look no further than second-medic.com because we give you access to qualified medical advice from a specialist.

The Autism Society outlines a number of signs that parents can use to determine whether or not they should take their child for an autism evaluation. The most common signs are social and communication issues, obsessions with specific objects, repetitive movements, resisting change; difficulty transitioning from one activity to another; difficulties organizing tasks or ideas; unusually intense reactions to sensory information (tactile, auditory); poor motor skills; difficulty with language-whether in speaking, reading comprehension and writing. Improvement is possible when diagnosed early.

If a doctor or therapist has recommended that you get a second opinion on your child's possible autism diagnosis, then it's important to find doctors and therapists in your area who offer this service.

The trouble with diagnosing autism in children is that every child is different, developing at their own pace and in various parts of the brain. The most significant difference between autistic and non-autistic children are social interactions, which include difficulty interacting with other people, strange eye contact, or reacting to emotions displayed by others. Another red flag would be repetitive behaviors. Overall, these signs and symptoms require significant active observation for a diagnosis.

Generally speaking, though the best way to manage kids with autism is by establishing an orderly schedule as far as possible so it will

A pediatrician will carry out a physical examination to look for any suspicious signs. There are currently no medical or blood tests that can formally diagnose autism. Diagnosis is based on reports from parents, usually in the form of a diagnosis by exclusion (i.e., ruling out other causes of the symptoms). The following are considered as red flags: Dramatic change in toilet training at an early age social delay (does not play well) Loss of words or language skills, even though there is nothing wrong with hearing Tantrums Self-harming behavior/signs of stress Abnormally strong reactions to certain sounds and textures, loud noises such as clinking.

When a child does not show any of these signs and symptoms, it doesn't necessarily mean he or she doesn't have autism. Consult with Second Medic opinion online consultation for more information.

The common sign is unusual delays in language development. They may seem ahead at times and will love to repeat words after you say them but then they start having trouble stringing together two-word phrases as they get older. It's also different from dyslexia in that autistic children are usually well-behaved instead of hyperactive so there's no fidgeting or interrupting others when someone else is talking. The classic test for autism is the "AQ" test which measures social awareness and communication skills among other things.

Importance of Hydration for Organs: How Water Keeps the Body Functioning

Water is the most essential nutrient for human survival, yet it is often the most neglected. Every cell, tissue and organ in the body depends on adequate hydration to function properly. The importance of hydration for organs becomes clear when we understand how even mild dehydration can disrupt critical physiological processes.

In India’s climate, with high temperatures and humidity in many regions, dehydration risk is especially high, making conscious hydration a daily health priority.

Why Water Is Vital for the Human Body

The human body is made up of approximately 60 percent water. This water:

transports nutrients and oxygen
regulates body temperature
removes waste products
supports metabolic reactions

Without adequate hydration, organ systems begin to struggle.

Hydration and Kidney Health

The kidneys are among the most hydration-dependent organs.

Proper hydration:

helps kidneys filter blood efficiently
flushes out toxins and waste
reduces risk of kidney stones

Chronic dehydration forces kidneys to concentrate urine, increasing strain and long-term damage risk. According to Indian Council of Medical Research data, dehydration is a major contributor to kidney stone formation in India.

Brain Function and Hydration

The brain is highly sensitive to hydration levels.

Even mild dehydration can cause:

headaches
difficulty concentrating
memory issues
irritability

Studies published in the Lancet show that dehydration negatively affects cognitive performance and mood, even before thirst becomes noticeable.

Heart and Circulatory System

Hydration plays a critical role in cardiovascular health.

Adequate water intake:

maintains blood volume
supports smooth circulation
reduces strain on the heart

Dehydration thickens blood, making the heart work harder and potentially increasing the risk of low blood pressure, dizziness and cardiovascular stress.

Digestive System and Hydration

Water supports digestion at every stage.

It helps:

break down food
absorb nutrients
prevent constipation

Chronic low water intake is linked to digestive discomfort, bloating and poor gut motility.

Liver Function and Detoxification

The liver relies on water to:

metabolise nutrients
detoxify harmful substances
support metabolic balance

Inadequate hydration slows detoxification processes and increases metabolic strain.

Muscle and Joint Health

Muscles and joints contain significant water content.

Hydration:

prevents muscle cramps
supports joint lubrication
reduces injury risk

Dehydrated muscles fatigue faster and recover more slowly.

Skin as an Organ and Hydration

The skin is the body’s largest organ.

Adequate hydration:

maintains skin elasticity
supports barrier function
reduces dryness and irritation

While water alone is not a cure for skin problems, chronic dehydration worsens skin health.

Hydration and Immune Function

Water supports immune health by:

enabling transport of immune cells
aiding removal of toxins
supporting lymphatic circulation

WHO recognises hydration as a foundational element of immune system support.

Effects of Dehydration on Multiple Organs

Dehydration affects the body systemically.

Common effects include:

fatigue
dizziness
reduced urine output
dark-coloured urine
dry mouth and eyes

Severe dehydration can lead to organ failure if untreated.

Why Dehydration Often Goes Unnoticed

Many people confuse thirst with hunger or fatigue.

Risk factors include:

busy work schedules
excessive caffeine intake
high temperatures
inadequate fluid intake

By the time thirst is felt, dehydration has already begun.

Hydration Needs Vary by Individual

Water requirements depend on:

age
body size
physical activity
climate
health conditions

General guidelines suggest 2–3 litres daily for adults, but individual needs may vary.

Hydration and Chronic Disease Prevention

Proper hydration supports prevention of:

kidney disease
urinary tract infections
constipation
heat-related illness

NITI Aayog and WHO highlight hydration as a basic preventive health measure.

Best Practices for Staying Hydrated

Effective hydration strategies include:

drinking water regularly throughout the day
increasing intake during heat or physical activity
consuming water-rich foods such as fruits and vegetables
limiting sugary and caffeinated beverages

Consistency matters more than quantity in a single sitting.

Signs You May Need More Water

Watch for:

frequent fatigue
headaches
dry skin
reduced urination
poor concentration

These are early indicators of dehydration.

Role of Preventive Health Awareness

Preventive healthcare focuses on simple daily habits.

Hydration:

costs nothing
supports every organ
reduces disease risk

Small habits deliver large long-term benefits.

When to Seek Medical Advice

Consult a healthcare professional if experiencing:

persistent dehydration symptoms
kidney or urinary issues
dizziness or fainting
chronic fatigue

Underlying conditions may require medical evaluation.

Conclusion

The importance of hydration for organs cannot be overstated. Water supports kidney filtration, brain function, heart circulation, digestion, immunity and overall metabolic balance. Even mild dehydration disrupts organ performance and increases health risks over time. In busy modern lifestyles, consciously prioritising daily hydration is one of the simplest and most effective ways to protect vital organs and maintain long-term health. Consistent water intake is not just a habit—it is a foundation for organ health and wellbeing.
