What is Anxiety Symptoms?
It starts with a flutter in your chest. Then, your palms get sweaty. Your mind starts racing, jumping from one worry to the next. You feel restless, on edge, and perhaps a little breathless. You tell yourself, “It’s just stress. I just need to relax.” But what if it isn’t just stress?
At Eskag Sanjeevani Hospitals, we see hundreds of patients who come to us convinced they are suffering from a mental health crisis. They describe classic anxiety symptoms—insomnia, heart palpitations, fatigue, and irritability. However, after a thorough medical investigation, a surprising number of them discover that their “anxiety” is actually a silent cry for help from their physical body.
We often separate the mind and the body, treating them as two different entities. But biologically, they are one system. When your physical health is off-balance, your mental state often takes the hit. This is why a full body checkup is one of the most important first steps in managing mental well-being.
In this guide, we will explore why your body might be tricking you into feeling anxious and how a routine full body checkup can give you the answers you desperately need.
Key Takeaways:
- Many physical conditions, such as thyroid disorders, anaemia, and vitamin deficiencies, can perfectly mimic the symptoms of severe anxiety.
- A full body checkup provides the necessary medical data to distinguish between psychological stress and physiological illness, ensuring you get the proper treatment.
- Eskag Sanjeevani Hospitals offers comprehensive health packages that inspect key biomarkers, helping you find the root cause of your unease.

When Body Issues Look Like Mind Issues
Anxiety is real, and it is a valid mental health condition. However, before you start therapy or anti-anxiety medication, it is medical best practice to rule out physical causes. This is where a full body checkup becomes an essential diagnostic tool.
Your brain relies on a precise balance of hormones, oxygen, and nutrients to keep you calm. If that balance is disrupted, your brain hits the panic button.
The Thyroid Connection
The most common culprit we see is the thyroid gland. This small butterfly-shaped gland in your neck regulates your metabolism. If it produces too much hormone (Hyperthyroidism), your body goes into overdrive. The symptoms? Racing heart, trembling hands, unexplained sweating, and nervousness.
These are identical to anxiety symptoms. Without a full body checkup, you might spend months treating “panic attacks” when you actually need medication to regulate your thyroid. Conversely, an underactive thyroid (Hypothyroidism) can cause brain fog and depression. A simple TSH test included in a full body checkup can clarify this instantly.
The Vitamin Deficiency Link
We often underestimate the power of vitamins. Vitamin B12 and Vitamin D are crucial for nerve health.
- Vitamin B12: A deficiency here can damage the myelin sheath (the protective covering of nerves), leading to sensations of tingling, brain fog, and severe anxiety.
- Vitamin D: Low levels of the “sunshine vitamin” are strongly linked to mood disorders and depression.
In a city like Kolkata, where many of us work indoors, these deficiencies are rampant. A full body checkup will measure these levels precisely.The Heart of the Matter
Palpitations—that feeling of your heart skipping a beat or pounding hard—are terrifying. They are a hallmark of panic attacks. But they are also symptoms of anaemia (low iron) or arrhythmias (irregular heartbeats).
If you are anaemic, your heart has to work double-time to pump oxygen. This physical stress feels exactly like emotional stress. A full body checkup includes a Complete Blood Count (CBC) to check your haemoglobin and often an ECG to check your heart rhythm, giving you peace of mind that your heart is physically strong.
What Exactly is a Full Body Checkup?
If you have never had one, the term might sound intense. But a full body checkup is simply a comprehensive screening process designed to evaluate the health of every major organ system in your body. It is preventative maintenance for humans.
The goal of a full body checkup is to catch “silent” problems before they become loud emergencies. For someone dealing with unexplained anxiety symptoms, this screening acts as a process of elimination. It tells us what is not wrong, so we can focus on what is.
The Full Body Check Up Procedure: What to Expect
Anxiety often makes us fear medical settings. We understand that. That is why at Eskag Sanjeevani, we ensure the full body check-up procedure is as smooth, quick, and comfortable as possible.
Here is how it typically works:
- Preparation: You will usually need to fast (no food or drink other than water) for 8 to 10 hours before the test. This ensures accurate blood sugar and cholesterol readings.
- Sample Collection: A phlebotomist will take a small blood sample. This is the most critical part, as your blood holds the secrets to your chemical balance. You will also provide a urine sample.
- Imaging and Scans: Depending on the specific full body checkup you choose, you might undergo an X-ray, an ECG (heart tracing), or an ultrasound. These are painless and non-invasive.
- The Doctor’s Review: Once the reports are ready, a physician reviews them with you. This is the moment of clarity where we connect the dots between your full body checkup results and your anxiety symptoms.
Decoding the Full Body Check Up Tests List
Patients often ask us what exactly we are looking for. While packages vary, a standard full body check-up test list relevant to anxiety will include:
- Complete Hemogram (CBC): To check for infection or anaemia (low iron causes fatigue and a racing heart).
- Thyroid Profile (T3, T4, TSH): To rule out hormonal imbalances triggering panic.
- Blood Sugar (Fasting & PP): Low blood sugar (hypoglycemia) can cause shaking, sweating, and confusion—symptoms often mistaken for a panic attack. High blood sugar (diabetes) causes fatigue and mood changes.
- Lipid Profile: Checks cholesterol. While not directly causing anxiety, heart health is vital for peace of mind.
- Liver and Kidney Function Tests: These organs filter toxins. If they are sluggish, toxins build up, affecting brain function and mood.
- Vitamin B12 & D3 Levels: Essential for checking nutritional causes of mental instability.
- Electrolytes: Imbalances in sodium or potassium can cause heart irregularities and mental confusion.
When you see this full body check-up tests list, you realise how many physical factors contribute to your mental state.
The Medical Perspective: Anxiety Nursing Diagnosis
In a hospital setting, healthcare professionals use specific language to care for you. When a patient is admitted with severe distress, nurses formulate an anxiety nursing diagnosis. This is a clinical judgment that guides how they care for you.
A key part of an anxiety nursing diagnosis involves looking for “related factors.” Nurses and doctors are trained to ask: Is this anxiety related to a situational crisis (stress), or is it related to a physiological factor (illness)?
By undergoing a full body checkup, you are helping your medical team refine this diagnosis. If your checkup shows high thyroid levels, your “anxiety” diagnosis shifts to a “thyroid management” plan. This shift is crucial because no amount of deep breathing will fix a thyroid storm, just as thyroid medication won’t fix workplace stress. A full body checkup provides the evidence needed to treat the root cause, not just the symptom.
Choosing the Right Full Body Check Up Package
At Eskag Sanjeevani Hospitals, we believe healthcare should be accessible. We have designed a full body check up package that covers all these essentials without being overwhelming.
When selecting a full body check up package, look for one that specifically includes thyroid and vitamin screening if your main concern is anxiety. Many basic packages might skip Vitamin D or B12 to keep costs low, but for someone feeling mentally drained, those are the most valuable markers.
Investing in a full body checkup is often cheaper than months of therapy or medications that might not be working because the physical root cause was missed. It is an investment in certainty.
Why Do We Ignore the Physical Signs?
We live in a high-pressure society. When we feel jittery or unable to sleep, we blame our jobs, our relationships, or our finances. We normalise feeling terrible. We tell ourselves, “I’ll get a full body checkup later.”
But your body keeps the score. If your blood sugar is crashing every afternoon, you will feel panicked. If your iron is low, you will feel depressed and tired. These are biological realities. By getting a full body checkup, you stop guessing and start knowing.
For healthy adults under 30, once every two years is usually sufficient. However, if you are over 30 or experiencing persistent issues like unexplained anxiety symptoms, fatigue, or weight changes, we recommend an annual full body checkup to stay ahead of potential health issues.
Yes, absolutely. When your blood sugar drops (hypoglycemia), your body releases adrenaline to try and raise it. This adrenaline surge causes shaking, sweating, a racing heart, and a feeling of impending doom—symptoms that are almost identical to a severe panic attack. A full body checkup includes a fasting glucose test to see if you.
Our comprehensive full body check up package typically includes a Complete Blood Count, Blood Sugar tests, Thyroid Profile, Lipid Profile, Liver and Kidney Function tests, and basic imaging like an ECG or Chest X-ray. We can also customise the package to include specific vitamin markers.
Not at all. The full body check up procedure is non-invasive. The only discomfort is a minor pinch during the blood sample collection. Our nursing staff at Eskag Sanjeevani are highly skilled and ensure the process is quick and as painless as possible.
No, you generally do not need a prescription for a preventive full body checkup. You can book a full body check up package directly with us. However, reviewing the results with one of our doctors is highly recommended to understand what the numbers mean for your health.
