Psoriasis: Types, Symptoms, Causes, Diagnosis, Treatment & Diet


Have you ever had red scaly patches on your knees or elbows? If so, then you may have had Psoriasis in some part of your life. Unfortunately, it is a long-term disease that still doesn’t have any cure. 

Psoriasis usually comes in phases. Initially, it tends to stay within the human body a little while. Then, the symptoms disappear before opting for remission. There are many recommended diagnoses to cure its symptoms. Apart from treatment, you can improve your eating habits to live better.

Types of Psoriasis

There are many indications for Psoriasis. Initially, you may experience dandruff-like scalings, and then you may see massive eruptions across your body. Medical professionals state that the lower back, elbow, knees, and heels are the most affected human body areas. 

Most of the types tend to go in phases. First, they appear in spots for a few weeks before causing massive eruptions within the body. The types of this disease are mentioned below:

Plaque Form

Plaque form is the most common type of this disease. It causes skinny red patches on different parts of the body along with silvery scales. This type can make you feel itchy, and you try to minimize it by putting water on it. However, the effect goes away just for a few minutes before returning. Elbows and knees are the ones that usually get affected by this type.

Nail Form

Apart from knees and elbows, nail form can also harm your nails. Regardless of it being a fingernail or a toenail, you will experience abnormal nail growth. Eventually, there may come a time when the nail completely dissociates itself from the nail bed. In extreme cases, it will disintegrate and experience discoloration.   

Guttate Form

Guttate is usually associated with young adults and kids. Bacterial infections like strep throat initiate this type before it covers the entire human body. Your arms or elbows may have to scale wounds to indicate this type. 

Inverse Form

The inverse form usually targets the skin of your groin and breasts. It creates patches of red skin that get worse if you start itching or sweating. Fungal infections initiate this type.

Pustular Form

Pustular form rarely occurs on a human body. However, in extreme cases, there is a huge possibility of this type reappearing in the body. It causes pus-filled wounds that cover large parts of the body. Hand palms and heels are two of the most affected body parts of this type.

Erythrodermic Form

The erythrodermic form is the least common type found in the human body. It covers your body with a red rash that gets worse with itching and sweating. 

Psoriatic Arthritis

Psoriatic Arthritis leads to swollen joints. Sometimes, swollen joints are the only symptoms found because of this type. However, in other cases, nails also experience changes. In addition, it causes uneasiness which may lead to permanent joint damage in severe cases.  


There are various symptoms that you can visualize to indicate signs of Psoriasis in your human body. Some of them are as follows:

  • Red patchy skin along with thick wounds.
  • Tiny scaling portions.
  • Dry skins that may cause itching.
  • Thickened nails separated from the nail bed.
  • Swollen joints

Causes of Psoriasis 

Numerous medical reports state that Psoriasis is an immune system that causes skin regeneration at a quicker rate. Unfortunately, in most common types, this transformation of cells results in red skin. 

Doctors are still finding it challenging to identify the reasons behind the malfunctioning of the immune system. In most cases, both genetics and the environment contribute to this development. 


Psoriasis patients may feel the effects of this disease for numerous years until an environmental factor comes into play and brings its symptoms back. The triggers of this disease include:

  • Skin or throat infections.
  • Weather (Environmental Factor)
  • Skin Injury or extreme sunburn.
  • Mental or physical stress.
  • Addiction to smoking.
  • Alcohol consumption. 
  • Taking certain medications such as lithium or tackling high blood pressure.
  • Quick removal of oral corticosteroids. 


Considering the severity of Psoriasis, a patient needs to undergo its diagnosis. Consider a doctor near your house and give him full details about your condition. Afterward, he will recommend you to experience its diagnosis. There are two aspects in which its diagnosis takes place. They are mentioned below:

Physical Exam

Doctors find it easy to make a diagnosis of Psoriasis, especially if the affected areas are:

  • Ears
  • Elbows
  • Knees
  • Nails 

Your doctor or medical panel will give you a physical exam. In that exam, he will ask about many things related to your disease and whether your family has symptoms. 

Laboratory Tests

Doctors may have a chance to undergo a biopsy. A biopsy is a process in which the doctor removes a specific piece of skin for testing purposes, so you do not have any skin infection. 


If you are a Psoriasis patient, consider yourself lucky. There are many treatment options for you to get out of this mess. Some treatments can control the abnormal growth of cells, whereas others ensure that the itching, redness, and dry skin go away. Your doctor will look into the best treatment considering your age, skin condition, injury, and other talking points. Common treatments of this disease include:

  • Steroids
  • Skin moisturizers
  • Vitamin A creams
  • Foods containing Vitamin D

If you have a severe case, doctors will undergo the following treatments:

Light Therapy

First, your doctor will put ultraviolet (UV) light on your skin to hamper the abnormal growth of cells. PUVA (Psoralen + ultraviolet light A) is an ideal treatment for this therapy.  


This treatment is only for severe patients. It can cause bone marrow and lung problems, so the doctor should be cautious in this therapy. In addition, there are further lab tests that the patient must undergo, alongside chest X-ray and liver biopsy.  

Retinoids (Vitamin A)

Retinoids are numerous forms of Vitamin A. The conditions can be gel, creams, liquids, and drugs. However, there can be side effects regarding this treatment, such as congenital disabilities. Therefore, pregnant women or newly born kids are prescribed not to take this treatment.

Retinoids are only for severe cases. There is a chance that they can respond to some treatments while being completely silent for the others. However, it may destroy your kidneys and disrupt your blood pressure. Therefore, the doctors visualize your health care when you undergo this treatment. 

Enzyme inhibitor 

Otezla is a recommended drug created to treat diseases like Psoriasis. It is a pill that stops the functionalities of a specific enzyme, which slows all other procedures resulting in inflammation. 


If you are a Psoriasis patient, you must be looking into your medication and the environment. But, should you also be looking into your plate? Absolutely.

A healthy diet enriched with vegetables and proteins will keep you safe from any life-threatening disease. However, if we talk about a Psoriasis patient, a bad eating habit will harm your skin. Unfortunately, there are no evaluations regarding the kind of food or liquid you should avoid to improve your physical condition. However, everything boils down to your food intake. 

Minimize Alcohol Consumption

There is no clear link between alcohol and Psoriasis. However, you should not drink heavily. It would help if you drank alcohol more than once a day. Heavy drinking results in ineffective treatments in which you are unable to respond to anything. Furthermore, you will find out that your skin gets better once you stop drinking heavily.

If you are in a severe condition or undergoing treatments, such as methotrexate, your doctor will recommend avoiding alcohol at all costs. 

A Gluten-Free Diet 

There are many contrasting views about the gluten-free diet’s impact on Psoriasis and your everyday life. As the thoughts are unclear, there is a requirement for more research in this regard. However, there are many success stories for those having a gluten-free diet and not others. 

If you are a patient with an inflammatory disease like this, you must have a good eating plan. This plan can be beneficial if your diet is sensitive to gluten. Having a gluten-free diet will allow you to disregard food containing grains like wheat. 

The negative impact is that these foods are beneficial for your health, whereas this disease may increase the probability of heart disease. Consider talking to your doctor before making changes to your eating habits.


To conclude, if you are in the earlier part of adulthood, you must be aware of Psoriasis’ consequences. In most cases, it occurs in a few aspects. If a person is having substantial medical issues, it can cover many portions of his body. The symptoms get healed and then return in no time.

Therefore, you need to stick to a proactive diet and stay safe. If your body is consuming adequate food, you are likely to be secure from this disease. In a world where there are food consumption issues due to lockdowns, a good diet is essential more than ever. Therefore, you must eat well and stay smart.
