i am a lady in my 20's but very skinny. in fact some people take me for a secondary school girl and this could be very embarrasing. Doctors in the house please advice me on the type of food and drugs that will make me add more flesh. I've been taking wate-on for quite some years to no effect.

pls whats wate-on ?

@poster Mawumawu is a good therapy for fattness take some today and u will be fat

@poster

you may take cyprohepatadine (periactin or cypron), its an antihistamine

it will make you really hungry and so get ready to eat

while hungry better take proteinous meals and less of carbohydrates/fats

@ifyalways

wate on  is a pharmaceutical that comes mostly in liquid form for people wishing to add weight

thank you ndubest.

I'll advice you to see a nutrisionist!!

Reduce your stree level and take vitamin supplements.

@ poster, it's not only you. I'm the second born in my family but every outsider think I'm the last born. Someone even asked if my brother -who is the last born- was my uncle whereas I'm older than him by five years. I used to take multivitamins daily, but it destabilized my periods , I just had to stop.

just reduce your level of activity and eat more i guess. if that doesn't work, just don't stress it. just look at the positive side and tell yourself that it's a compliment to look younger

how slim is your slim?
what is your body mass index?(BMI)
some tips on gaining weight the right way are :

Calories: Our bodies have a need for a set number of calories each day. This need is based on your age, gender, height, weight, and activity level. In order to gain weight, you will need to take in more calories than your body needs to maintain your current weight.

Nutrients: There are six essential nutrients that our bodies need to function; they are protein, carbohydrates, fat, vitamins, minerals, and water. Each of these nutrients has its own function and is needed in different amounts. The way to get them is through the foods that we eat, and in some cases, by the supplements that we take. Your goal for gaining weight will be to eat a well-balanced diet in order to get all of these nutrients in. The food groups that you will want to focus on increasing are:
Starch – This is a great group to get calories from. Try to eat foods made with whole wheat flour. Have bread, rice, pasta, potatoes, cereals, beans, and starchy vegetables (corn and peas) with all of your meals.
Fat – You will get a lot of calories for a small amount of food when you add fat to your meals and snacks. The goal here is to avoid the foods with the trans fat and have the ones with little or no saturated fat. You can use nuts as a snack or add them to your meals, cook with olive or canola oil, and use peanut butter as a snack or with your meal. It's important to get foods with omega-3 fats, so include fatty fish (salmon, albacore tuna, mackerel, lake trout, herring, sardines), flax seeds, and walnuts. Be careful not to go overboard with fat because too much is not good for your health. Stick with the guidelines of less than 30% of your calories coming from fat.
Meat - The protein in meat is great for building muscle. Foods in this group includes chicken, turkey, seafood, eggs, pork, cheese, and beef.
Diary – Be sure to include low fat (1% or 2%) milk and/or yogurt into your diet. You can add some nuts or flax seeds to your yogurt to have as a snack, and you can have a cup of milk with your meals for the added calories.

Fruit – There are lots of health benefits to fruit, and you can have them with some of the other foods to boost the calories. Fruit with peanut butter or cheese are great snacks with lots of calories.

Vegetables – As always, keep your vegetable intake up for the great health benefits that they provide. Your diet needs the balance of each of the groups for optimal health.

get a frequency:
It may be helpful to eat every couple of hours in order to get enough food and calories in. Set a timer on your cell phone or put it in your appointment book to remind you to eat.

supplements:
If you can't get the calories in from food alone, you can consider using a supplement.

Ensure in between meals

Adequate rest and enough sleep.
